Hi I'm trying to send a RS232 command to a PAC\r\n\r\nI've confirmed the Command, by sending it to a standard PC-Int. This works fine.\r\n\r\nHowever, sending it to a PAC does not work ... \r\n\r\nDo I need to initialize the PAC so its RS232 ports are open ??\r\nif So how do I do this, it does not makes sense via the logic programming, as it requires me to set a serial port num, and a com port num.\r\n\r\nCan one of the CIS gurus shed some light on this.\r\n\r\nFYI\r\nthe command I am sending, was derrived using the "CBUS-PUBREL" dosument, as I mentioned it works ok for sending RS232 to the PC-Int. Is the protocol different for the PAC ??\r\n\r\nCome to think of it:-\r\nI will also require the PAC to send RS232 commands, I will have the same delima in the logic programming. Do I need to open/close serial ports on the PAC, if so, how do I write the command.
