Close ASCII communications on CN3B
Returns 0 if successful, or -1 on an error.
Returns a character from the ASCII receive buffer.
Returns character if successful, or 0 on an error.
long SerialOpen(long baudrate);
Open ASCII communications on CN3B at the specified baud rate
Returns 0 if successful, or -1 on an error.
char SerialPutChar(char character);
Inserts a character into the ASCII transmit buffer.
Returns 0 if successful, or -1 on an error.
ATTENTION
!
This function must be called in your main program
execution loop if the program is to react to a Stop
command. If this is not used (as in the previous
examples), the Stop command will be ignored. It is
your responsibility to write the program to check and
react properly to this event!
