comf(portno, txrate, rxrate, format)
portno: Communication port number (0 to B).
txrate: Transmit data rate.
txrate: Receive data rate.
format: Data format code.
Used to select the transmit and receive data rate and the format of a serial line.
Operation
Function comf() allocates the line to the automatic control function and configures the port. Once the line has been
initialised, it cannot be allocated to another user (CNC function, etc.).
The function comf(portno, txrate, rxrate, 0) deallocates the line and makes it available for another user.
! CAUTION
The transmit and receive baud rates must always be the same.
When initialising a line on the CNC processor card (line 2 or 3), it is necessary to call
function comf() in a task %TF.
Value of arguments «txrate» and «rxrate»
The values correspond to baud rates.
