+** THIS BEAN MODULE IS GENERATED BY THE TOOL. DO NOT MODIFY IT.
+** Filename : COM0.C
+** Project : RTOSDemo
+** Processor : MC9S12DP256BCPV
+** Beantype : AsynchroSerial
+** Version : Bean 02.231, Driver 01.08, CPU db: 2.87.283
+** Compiler : Metrowerks HC12 C Compiler
+** Date/Time : 19/06/2005, 15:07
+** Abstract :
+** This bean "AsynchroSerial" implements an asynchronous serial
+** communication. The bean supports different settings of
+** parity, word width, stop-bit and communication speed,
+** user can select interrupt or polling handler.
+** Communication speed can be changed also in runtime.
+** The bean requires one on-chip asynchronous serial channel.
+** Settings :
+** Serial channel : SCI0
+**
+** Protocol
+** Init baud rate : 38400baud
+** Width : 8 bits
+** Stop bits : 1
+** Parity : none
+** Breaks : Disabled
+**
+** Registers
+** Input buffer : SCI0DRL [207]
+** Output buffer : SCI0DRL [207]
+** Control register : SCI0CR1 [202]
+** Mode register : SCI0CR2 [203]
+** Baud setting reg. : SCI0BD [200]
+** Special register : SCI0SR1 [204]
+**
+** Input interrupt
+** Vector name : INT_SCI0
+** Priority : 1
+**
+** Output interrupt
+** Vector name : INT_SCI0
+** Priority : 1

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