6 Changes since tio v1.29:
10 * Update man page and bash completion
16 * ONLCRNL: change the method to map NL to CR-NL
20 Changes since tio v1.28:
22 * Add mapping flags INLCRNL and ODELBS
24 The following new mapping flags are added:
26 INLCRNL: Map NL to CR-NL on input.
27 ODELBS: Map DEL to BS on output.
29 Flags requested and tested by Jan Ciger (janoc).
33 Changes since tio v1.27:
39 * Add snap status to README.md
41 * Add README.md to prettify GitHub page
47 * Add missing header file under musl-libc
49 Musl's inclusion tree slightly differs from glibc, therefore TCGETS2 is
50 not reachable through sys/ioctl.h, so asm/ioctls.h needs to be included
55 * Fix grammar and typos
59 Changes since tio v1.26:
63 * Add support for setting non-standard baudrates
65 Support for non-standard baudrate settings will be automatically enabled
66 if the termios2 interface is detected available. However, to play it
67 safe, the old and widely supported termios interface will still be used
68 when setting standard baudrates.
76 Changes since tio v1.25:
80 Make stdin behave more raw'ish. In particular, don't
81 translate CR -> NL on input.
83 * Add special character map feature
85 Add a --map option which allows mapping special characters, in particular CR and
86 NL characters which are used in various combinations on various platforms.
100 Changes since tio v1.24:
102 * Fix error applying new stdout settings
104 On Fedora 26 tio will quit with the following error message:
106 "Error: Could not apply new stdout settings (Invalid argument)"
108 In case of Fedora, it turns out that the new stdout settings used are a
109 bit too aggressive because an empty termios structure is used. To remedy
110 this we reuse the existing stdout settings and only reconfigure the
111 specific options we need to make a "raw" stdout configuration.
113 * Remove unused pkgconfig in configure
117 Remove unused variable.
121 Changes since tio v1.23:
123 * Optimize clear screen command
125 Replaced system call with inline ANSI/VT100 clear screen code sequence
127 * Fix bash completion installation
129 Fixed the configure script to avoid that the bash completion script gets
130 installed outside of the prefix location. The default install location
131 is now $prefix/share/bash-completion/completions.
133 Use the configure option '--with-bash-completion-dir=PATH' if you need
134 to install the bash completion script elsewhere.
138 * Add missing commas in conditional sentences
142 Changes since tio v1.22:
144 * Update copyright headers
152 Changes since tio v1.21:
154 * Update man page date
156 * Update copyright year
160 * Update README and man page
164 Changes since tio v1.20:
166 * Add support for hexadecimal mode
168 A new key command 'ctrl-t h' is introduced which toggles between
169 hexadecimal mode and normal mode. When in hexadecimal mode data received
170 will be printed in hexadecimal.
172 * Do not distribute src/bash_completion/tio
174 Since the bash completion tio script is now autogenerated from tio.in it
175 should not be distributed in the tarball.
177 * Add missing forward flag
179 * Update AUTHORS file
183 * 'ctrl-t b' to send serial break.
187 * Removed git commit references from ChangeLog
189 ChangeLog is primary useful for users who don't have the git repository
192 Replace git commit references with version numbers; or if the change
193 only cleans up another change with no release in between, remove the
194 changelog item completely.
198 Changes since tio v1.19:
200 * Added more error handling of terminal calls
202 Also removed duplicate terminal flushing calls.
204 * Revert "Added support for non-standard baud rates"
206 This reverts a change made in v1.18.
208 Reverting because supporting non-standard or arbitrary baud rates is
209 troublesome because the c library provides no means of doing so and even
210 if bare metal linux kernel interface is used it will not work on all
211 Linux kernels version.
215 Changes since tio v1.18:
217 * Rearranged key commands
219 Rearranged the key commands:
221 ctrl-t c (clear screen) is now
222 ctrl-t l which is similar to the well known shell ctrl-l
224 ctrl-t i (show settings information) is now
225 ctrl-t c (show configuration)
227 Updated man page accordingly.
229 * Added "ctrl-t c" key command to clear screen
233 Changes since tio v1.17:
237 * Added support for non-standard baud rates
239 Only enabled when possible, that is, when the BOTHER definition is
242 It is untested but it should work as described here:
243 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=683826
245 Some Cypress USB<->serial devices supposedly supports arbitrary speeds.
247 * Generate baudrate switch cases based on detection
249 Support a single source of baud rate configuration as discussed in
250 https://github.com/tio/tio/issues/45 .
252 To do so, autogeneration of the switch cases which do the baud rate
253 option value check and configuration/conversion in tty_configure() is
254 introduced via a single macro.
256 Just to be safe, this change also enables configure detection of all
257 baud rates, including the ones previously assumed supported by most/all
262 * Exit when not a tty device in autoconnect mode
266 * Added non-standard baud rates that are defined on FreeBSD
268 * Capitalized "GitHub" in README
272 Changes since tio v1.16:
274 * Compacted tty_configure() a bit
276 * Fixed automatic baud rate enablement
280 * Added autodetection of available baud rates
282 Various platforms support different baud rates.
284 To avoid adding platform specific handling generic baud rate detection
285 tests are introduced in the configure script. Successfully detected baud
286 rates are automatically enabled. This applies to both the C code and the
287 bash completion script.
290 Baud rates below 57600 are defined by POSIX-1 and supported by most
291 platforms so only baud rate 57600 and above are tested.
293 * Updated bash-completion
295 * Fixed printf() format type
297 * Added Travis build configuration
301 * Generated bash completion at configure time
303 * Reduce code duplication in baud rate detection
305 * Add support for baud rates 200 and 1800
307 * Fixed baudrate type
311 Changes since tio v1.15:
317 * Removed obsolete packaging files
319 * Removed use of deprecated bzero()
323 Changes since tio v1.14:
325 * Removed + to remove potential confusion
327 * Added input digit checks
329 * Fixed license string
331 * Introduced tty_configure()
333 Moved tty configuration actions to tty_configure() in tty.c. This way
334 options.c is strictly about parsing options nothing else.
336 * Function names cleanup
338 * Updated AUTHORS file
340 Added Nick who created the new tio package for Arch Linux.
342 * Fixed tx/rx counters type
346 * Include config.h before standard headers
348 Large file support was meant to be enabled in v1.11.
349 This change enables it for real.
353 Changes since tio v1.13:
355 * Fixed tio_printf macro
359 Fixed launch hints not being printed in no autoconnect mode.
361 * Added 'ctrl-t ?' to list available commands
363 * Fixed log mechanism
365 To avoid echoing only log what is received from tty device.
367 * Improved tio output
369 Added titles and indentation to commands output for clearer separation
370 when firing commands repeatedly.
372 Also added print of tio version and quit command hint at launch.
374 * Cleaned up tio print mechanism
380 "allow" is a transitive verb, which requires an object,
381 so "allow to <verb>" is ungrammatical.
387 Changes since tio v1.12:
389 * Fixed some error prints
391 * Fixed error printing for no autoconnect mode
393 Always print errors but only print silent errors when in no autoconnect
396 * Added key command for showing session settings
398 A new key command "ctrl-t i" is added to allow the user to display the
399 various session settings information (baudrate, databits, log file, etc.).
401 This is useful in case you have a running session but have forgotten
402 what the settings are.
406 Changes since tio v1.11:
408 * Consolidated command key handling
410 * Moved delay mechanism into separate function
412 * Retired obsolete usleep()
414 Replaced with nanosleep()
416 * Added simple tx/rx statistics command (ctrl-t s)
418 To display the total number of bytes transmitted/received simply perform the
419 'ctrl-t s' command sequence.
421 This feature can be useful when eg. trying to detect non-printable
424 * Further simplification of key handling
426 Changed so that the "ctrl-t ctrl-t" sequence is now simply "ctrl-t t" to
427 send the ctrl-t key code. This is inspired by screen which does similar
428 to send its command key code (ctrl-a a).
430 This change also eases adding new key commands if needed.
432 Updated man page accordingly.
434 * Cleaned up and simplified key handling
438 * Insert output delay only if something was output
442 Changes since tio v1.10:
444 * Enabled large file support (LFS)
446 Added autotools AC_SYS_LARGEFILE to support 64 bit file size handling.
452 Changes since tio v1.9:
454 * Introduced lock on device file
456 Tio will now test for and obtain an advisory lock on the tty device file
457 to prevent starting multiple sessions on the same tty device.
463 * Treat EOF on stdin as error
467 Changes since tio v1.8:
469 * Cleanup of error handling
471 Introduced consistent way of handling errors and printing error messages.
473 Also upgraded some warnings to errors.
475 * Updated localtime() error message
481 * Fix error handling for select()
483 Previously the error handling code for select() was unreachable.
485 * Removed unneeded quotes from AM_CFLAGS
489 * Fixed setting "tainted"
491 Set "tainted" if and only if any character was read from the device.
493 Ctrl-t is no longer sent to the device on exit, so the trick to avoid
494 its echo is not necessary.
496 Characters read from stdin don't directly affect output, so they
497 shouldn't enable "tainted".
499 * Used \r in color_printf()
501 \033[300D is an unusual way to move the cursor back to column 1.
502 Use straightforward \r instead.
504 * Added missing \r\n to warning messages
506 \n alone is not enough, because the terminal is in raw mode.
510 Changes since tio v1.7:
512 * Fixed enablement of compiler warnings
514 * Fixed log_open() prototype
516 * Fixed index error wrt ctrl-t detection
518 * Fixed handling of ctrl-t
520 Before, when exercising the quit key sequence (ctrl-t + q) the ctrl-t code
521 (0x14) would be sent.
523 This is now fixed so that it is not sent.
525 However, in case it is needed to send ctrl-t to the device it is possible by
526 simply repeating the ctrl-t.
528 Meaning, ctrl-t + ctrl-t = ctrl-t sent to device.
530 * Improved error handling
532 Fixes a memory leak and avoids aggressive busy looping when problems
533 accessing tty device.
535 * Removed redundant log_close() call
537 * Enabled compiler warnings
541 * Stopped copying arguments to fixed-size buffers
543 Don't needlessly copy command-line arguments into fixed-size buffers.
545 Previously the program crashed if an overlong pathname was provided on
546 the command line. Also, some systems (such as GNU Hurd) don't define
549 * Added const to log_open() prototype
551 * Completed the ^g to ^t transition
553 In v1.7 the escape key was changed from ^g to ^t, but some
554 code and comments still referred to the old key.
556 * Used HTTPS for tio.github.io
558 * Man page beautification
560 * Bumped date in man page
562 * Improve man page formatting
564 Use regular font for metacharacters such as "[]", "," or "|";
565 use italic font for metavariables.
567 * Fixed hyphen vs minus vs em-dash confusion in man page
570 \- prints as minus sign;
571 \em prints as em-dash.
575 Changes since tio v1.6:
577 * Changed escape key from ^g to ^t
579 After renaming to "tio" it makes sense to change the escape key
580 accordingly. Hence, the new escape key is ^t.
582 Meaning, in session, its now ctrl-t + q to quit.
586 * Fixed silly "tio or tio" in man page
