6 Changes since tio v1.30:
14 * Clarify the input/output variable names (No-op change)
16 * Organize options the same sequence they are mentiond in cmdline help.
20 * Map CR->NL locally on output instead of using tio.c_oflag |= OCRNL.
22 This mostly is intended to have local echo output exactly what is sent
23 to the remote endpoint.
24 A nice side-effect is, that it also fixes tty-implementations, that can't
25 deal with the OCRNL flag on tio.c_oflag.
27 * Provide local-echo option.
29 Can be switched on with -e on the command line.
30 Can be toggled with Ctrl t e while program is running.
32 * Write to logfile as soon as we have the data, don't buffer.
34 Logfiles are important to see what happend, in particular if something
35 unexpected happened; so we want to make sure that the logfile is flushed
38 Before this change, the logfile was typically written at the end in
39 a large chunk as the default (large) buffering applied. Now, characters are
40 written out ASAP, so it is possible to get a live-view with a
45 Changes since tio v1.29:
49 * Update man page and bash completion
55 * ONLCRNL: change the method to map NL to CR-NL
59 Changes since tio v1.28:
61 * Add mapping flags INLCRNL and ODELBS
63 The following new mapping flags are added:
65 INLCRNL: Map NL to CR-NL on input.
66 ODELBS: Map DEL to BS on output.
68 Flags requested and tested by Jan Ciger (janoc).
72 Changes since tio v1.27:
78 * Add snap status to README.md
80 * Add README.md to prettify GitHub page
86 * Add missing header file under musl-libc
88 Musl's inclusion tree slightly differs from glibc, therefore TCGETS2 is
89 not reachable through sys/ioctl.h, so asm/ioctls.h needs to be included
94 * Fix grammar and typos
98 Changes since tio v1.26:
102 * Add support for setting non-standard baudrates
104 Support for non-standard baudrate settings will be automatically enabled
105 if the termios2 interface is detected available. However, to play it
106 safe, the old and widely supported termios interface will still be used
107 when setting standard baudrates.
115 Changes since tio v1.25:
119 Make stdin behave more raw'ish. In particular, don't
120 translate CR -> NL on input.
122 * Add special character map feature
124 Add a --map option which allows mapping special characters, in particular CR and
125 NL characters which are used in various combinations on various platforms.
139 Changes since tio v1.24:
141 * Fix error applying new stdout settings
143 On Fedora 26 tio will quit with the following error message:
145 "Error: Could not apply new stdout settings (Invalid argument)"
147 In case of Fedora, it turns out that the new stdout settings used are a
148 bit too aggressive because an empty termios structure is used. To remedy
149 this we reuse the existing stdout settings and only reconfigure the
150 specific options we need to make a "raw" stdout configuration.
152 * Remove unused pkgconfig in configure
156 Remove unused variable.
160 Changes since tio v1.23:
162 * Optimize clear screen command
164 Replaced system call with inline ANSI/VT100 clear screen code sequence
166 * Fix bash completion installation
168 Fixed the configure script to avoid that the bash completion script gets
169 installed outside of the prefix location. The default install location
170 is now $prefix/share/bash-completion/completions.
172 Use the configure option '--with-bash-completion-dir=PATH' if you need
173 to install the bash completion script elsewhere.
177 * Add missing commas in conditional sentences
181 Changes since tio v1.22:
183 * Update copyright headers
191 Changes since tio v1.21:
193 * Update man page date
195 * Update copyright year
199 * Update README and man page
203 Changes since tio v1.20:
205 * Add support for hexadecimal mode
207 A new key command 'ctrl-t h' is introduced which toggles between
208 hexadecimal mode and normal mode. When in hexadecimal mode data received
209 will be printed in hexadecimal.
211 * Do not distribute src/bash_completion/tio
213 Since the bash completion tio script is now autogenerated from tio.in it
214 should not be distributed in the tarball.
216 * Add missing forward flag
218 * Update AUTHORS file
222 * 'ctrl-t b' to send serial break.
226 * Removed git commit references from ChangeLog
228 ChangeLog is primary useful for users who don't have the git repository
231 Replace git commit references with version numbers; or if the change
232 only cleans up another change with no release in between, remove the
233 changelog item completely.
237 Changes since tio v1.19:
239 * Added more error handling of terminal calls
241 Also removed duplicate terminal flushing calls.
243 * Revert "Added support for non-standard baud rates"
245 This reverts a change made in v1.18.
247 Reverting because supporting non-standard or arbitrary baud rates is
248 troublesome because the c library provides no means of doing so and even
249 if bare metal linux kernel interface is used it will not work on all
250 Linux kernels version.
254 Changes since tio v1.18:
256 * Rearranged key commands
258 Rearranged the key commands:
260 ctrl-t c (clear screen) is now
261 ctrl-t l which is similar to the well known shell ctrl-l
263 ctrl-t i (show settings information) is now
264 ctrl-t c (show configuration)
266 Updated man page accordingly.
268 * Added "ctrl-t c" key command to clear screen
272 Changes since tio v1.17:
276 * Added support for non-standard baud rates
278 Only enabled when possible, that is, when the BOTHER definition is
281 It is untested but it should work as described here:
282 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=683826
284 Some Cypress USB<->serial devices supposedly supports arbitrary speeds.
286 * Generate baudrate switch cases based on detection
288 Support a single source of baud rate configuration as discussed in
289 https://github.com/tio/tio/issues/45 .
291 To do so, autogeneration of the switch cases which do the baud rate
292 option value check and configuration/conversion in tty_configure() is
293 introduced via a single macro.
295 Just to be safe, this change also enables configure detection of all
296 baud rates, including the ones previously assumed supported by most/all
301 * Exit when not a tty device in autoconnect mode
305 * Added non-standard baud rates that are defined on FreeBSD
307 * Capitalized "GitHub" in README
311 Changes since tio v1.16:
313 * Compacted tty_configure() a bit
315 * Fixed automatic baud rate enablement
319 * Added autodetection of available baud rates
321 Various platforms support different baud rates.
323 To avoid adding platform specific handling generic baud rate detection
324 tests are introduced in the configure script. Successfully detected baud
325 rates are automatically enabled. This applies to both the C code and the
326 bash completion script.
329 Baud rates below 57600 are defined by POSIX-1 and supported by most
330 platforms so only baud rate 57600 and above are tested.
332 * Updated bash-completion
334 * Fixed printf() format type
336 * Added Travis build configuration
340 * Generated bash completion at configure time
342 * Reduce code duplication in baud rate detection
344 * Add support for baud rates 200 and 1800
346 * Fixed baudrate type
350 Changes since tio v1.15:
356 * Removed obsolete packaging files
358 * Removed use of deprecated bzero()
362 Changes since tio v1.14:
364 * Removed + to remove potential confusion
366 * Added input digit checks
368 * Fixed license string
370 * Introduced tty_configure()
372 Moved tty configuration actions to tty_configure() in tty.c. This way
373 options.c is strictly about parsing options nothing else.
375 * Function names cleanup
377 * Updated AUTHORS file
379 Added Nick who created the new tio package for Arch Linux.
381 * Fixed tx/rx counters type
385 * Include config.h before standard headers
387 Large file support was meant to be enabled in v1.11.
388 This change enables it for real.
392 Changes since tio v1.13:
394 * Fixed tio_printf macro
398 Fixed launch hints not being printed in no autoconnect mode.
400 * Added 'ctrl-t ?' to list available commands
402 * Fixed log mechanism
404 To avoid echoing only log what is received from tty device.
406 * Improved tio output
408 Added titles and indentation to commands output for clearer separation
409 when firing commands repeatedly.
411 Also added print of tio version and quit command hint at launch.
413 * Cleaned up tio print mechanism
419 "allow" is a transitive verb, which requires an object,
420 so "allow to <verb>" is ungrammatical.
426 Changes since tio v1.12:
428 * Fixed some error prints
430 * Fixed error printing for no autoconnect mode
432 Always print errors but only print silent errors when in no autoconnect
435 * Added key command for showing session settings
437 A new key command "ctrl-t i" is added to allow the user to display the
438 various session settings information (baudrate, databits, log file, etc.).
440 This is useful in case you have a running session but have forgotten
441 what the settings are.
445 Changes since tio v1.11:
447 * Consolidated command key handling
449 * Moved delay mechanism into separate function
451 * Retired obsolete usleep()
453 Replaced with nanosleep()
455 * Added simple tx/rx statistics command (ctrl-t s)
457 To display the total number of bytes transmitted/received simply perform the
458 'ctrl-t s' command sequence.
460 This feature can be useful when eg. trying to detect non-printable
463 * Further simplification of key handling
465 Changed so that the "ctrl-t ctrl-t" sequence is now simply "ctrl-t t" to
466 send the ctrl-t key code. This is inspired by screen which does similar
467 to send its command key code (ctrl-a a).
469 This change also eases adding new key commands if needed.
471 Updated man page accordingly.
473 * Cleaned up and simplified key handling
477 * Insert output delay only if something was output
481 Changes since tio v1.10:
483 * Enabled large file support (LFS)
485 Added autotools AC_SYS_LARGEFILE to support 64 bit file size handling.
491 Changes since tio v1.9:
493 * Introduced lock on device file
495 Tio will now test for and obtain an advisory lock on the tty device file
496 to prevent starting multiple sessions on the same tty device.
502 * Treat EOF on stdin as error
506 Changes since tio v1.8:
508 * Cleanup of error handling
510 Introduced consistent way of handling errors and printing error messages.
512 Also upgraded some warnings to errors.
514 * Updated localtime() error message
520 * Fix error handling for select()
522 Previously the error handling code for select() was unreachable.
524 * Removed unneeded quotes from AM_CFLAGS
528 * Fixed setting "tainted"
530 Set "tainted" if and only if any character was read from the device.
532 Ctrl-t is no longer sent to the device on exit, so the trick to avoid
533 its echo is not necessary.
535 Characters read from stdin don't directly affect output, so they
536 shouldn't enable "tainted".
538 * Used \r in color_printf()
540 \033[300D is an unusual way to move the cursor back to column 1.
541 Use straightforward \r instead.
543 * Added missing \r\n to warning messages
545 \n alone is not enough, because the terminal is in raw mode.
549 Changes since tio v1.7:
551 * Fixed enablement of compiler warnings
553 * Fixed log_open() prototype
555 * Fixed index error wrt ctrl-t detection
557 * Fixed handling of ctrl-t
559 Before, when exercising the quit key sequence (ctrl-t + q) the ctrl-t code
560 (0x14) would be sent.
562 This is now fixed so that it is not sent.
564 However, in case it is needed to send ctrl-t to the device it is possible by
565 simply repeating the ctrl-t.
567 Meaning, ctrl-t + ctrl-t = ctrl-t sent to device.
569 * Improved error handling
571 Fixes a memory leak and avoids aggressive busy looping when problems
572 accessing tty device.
574 * Removed redundant log_close() call
576 * Enabled compiler warnings
580 * Stopped copying arguments to fixed-size buffers
582 Don't needlessly copy command-line arguments into fixed-size buffers.
584 Previously the program crashed if an overlong pathname was provided on
585 the command line. Also, some systems (such as GNU Hurd) don't define
588 * Added const to log_open() prototype
590 * Completed the ^g to ^t transition
592 In v1.7 the escape key was changed from ^g to ^t, but some
593 code and comments still referred to the old key.
595 * Used HTTPS for tio.github.io
597 * Man page beautification
599 * Bumped date in man page
601 * Improve man page formatting
603 Use regular font for metacharacters such as "[]", "," or "|";
604 use italic font for metavariables.
606 * Fixed hyphen vs minus vs em-dash confusion in man page
609 \- prints as minus sign;
610 \em prints as em-dash.
614 Changes since tio v1.6:
616 * Changed escape key from ^g to ^t
618 After renaming to "tio" it makes sense to change the escape key
619 accordingly. Hence, the new escape key is ^t.
621 Meaning, in session, its now ctrl-t + q to quit.
625 * Fixed silly "tio or tio" in man page
