+** Abstract :\r
+** This bean "AsynchroSerial" implements an asynchronous serial\r
+** communication. The bean supports different settings of \r
+** parity, word width, stop-bit and communication speed,\r
+** user can select interrupt or polling handler.\r
+** Communication speed can be changed also in runtime.\r
+** The bean requires one on-chip asynchronous serial channel.\r
+** Settings :\r
+** Serial channel : SCI0\r
+**\r
+** Protocol\r
+** Init baud rate : 38400baud\r
+** Width : 8 bits\r
+** Stop bits : 1\r
+** Parity : none\r
+** Breaks : Disabled\r
+**\r
+** Registers\r
+** Input buffer : SCI0DRL [207]\r
+** Output buffer : SCI0DRL [207]\r
+** Control register : SCI0CR1 [202]\r
+** Mode register : SCI0CR2 [203]\r
+** Baud setting reg. : SCI0BD [200]\r
+** Special register : SCI0SR1 [204]\r
+**\r
+** Input interrupt\r
+** Vector name : INT_SCI0\r
+** Priority : 1\r

+** Method : COM0_SetBaudRateMode (bean AsynchroSerial)\r
+**\r
+** Description :\r
+** This method changes the channel communication speed (baud\r
+** rate). This method can be used only if you specify a list\r
+** of possible period settings at design time (see <Timing\r
+** dialog box> - Runtime setting - from a list of values).\r
+** Each of these settings constitutes a mode and Processor\r
+** Expert^[TM] assigns them a mode identifier. The prescaler\r
+** and compare values corresponding to each mode are\r
+** calculated at design time. You may switch modes at\r
+** runtime by referring only to a mode identifier. No\r
+** run-time calculations are performed, all the calculations\r
+** are performed at design time.\r
+** Parameters :\r
+** NAME - DESCRIPTION\r
+** Mod - Timing mode to set\r
+** Returns :\r
+** --- - Error code, possible codes:\r
+** ERR_OK - OK\r
+** ERR_SPEED - This device does not work in\r
