mmAopen <MMZ_RAB.LIB>
NOTE: MMZ_RAB.LIB functions are generally not reentrant.
SYNTAX: int mmAopen(unsigned qBaud)
DESCRIPTION: User function for
Initializing serial port A as a Modbus Master.
This function must reside in your application code.
Typical code for this function would be the following;
int mmAopen(unsigned qBaud)
{
// Open the serial port. THIS MUST BE DONE PRIOR TO SETTING THE
// DATA BITS AND PARITY SETTINGS.
if (serAopen(qBaud))
{
// setup parity. Either PARAM_OPARITY, PARAM_EPARITY, PARAM_NOPARITY,
// or PARAM_2STOP

// setup data bits. Either PARAM_7BIT, or PARAM_8BIT
serAdatabits(PARAM_8BIT);
// Set the Serial port mode. Used for Zworld SBC's only.

PARAMETER1: slave address.
PARAMETER2: baud rate (bits per second).

mmArx <MSZ_RAB.LIB>
NOTE: MMZ_RAB.LIB functions are generally not reentrant.
SYNTAX: void mmArx (void)
DESCRIPTION: User defineable function for disabling the rs485
transmitter. This function is needed in your application
code. If you are doing RS232, you need only to have
an empty function like
void mmArx(void)
{
}
For rs485 control, you can do the following;
EXAMPLE: void mmArx(void)
{
// Ensure that all the data has bent sent.
while (serAwrUsed() || \
BitRdPortI(SASR,2) || \
BitRdPortI(SASR,3));
// Turn off the RS485 transmitter by doing the following;
// PORT: The parrallel port (PADR,PBDR,PCDR etc)
// PORTShadow: The Shadow register of the port
// OFF_VALUE: 1 or 0
// PORT_BIT: parrallel port bit (0-7)
BitWrPortI(PORT,&PORTShadow, OFF_VALUE, PORT_BIT);
// If your product is a Zworld SBC, you can do the following
ser485Rx();
// Flush out the serial port read buffer, so you are ready for
// the next packet.
