Hi,

sounds like a misconfiguration of the baud rate. The whole configuration in your startup script may look like this (adapt to your device):
drvAsynSerialPortConfigure("TESTPORT","/dev/ttyS0",0,0,0)
asynSetOption("TESTPORT", -1, "baud", "9600")
asynSetOption("TESTPORT", -1, "bits", "8")
asynSetOption("TESTPORT", -1, "parity", "none")
asynSetOption("TESTPORT", -1, "stop", "1")
asynSetOption("TESTPORT", -1, "clocal", "Y")
asynSetOption("TESTPORT", -1, "crtscts", "N")

If you are communicating between two hosts, make sure to use a null modem adapter / cable.

Best regards,
Christoph

Hi all,

    I intend to output "FA02AF" using stream.

    The IOC worked well but no effect. I checked the output using serial assistant in Win7.

    I got a indescribable string, not the FA02AF. Actually when I echo FA02AF >/dev/ttyS0, it seems well.

I have no idea about these. Could someone give me some advice.

mydev.proto:
_________________

Terminator=CR;

AS{

      out "FA02AF"

}

mydev.db:

__________________

record(ao,"AS")

{

    field(SCAN, "Passive")

    field(DTYP, "stream")

    field(OUT, "@mydev.proto AS $(PORT)")

}

Regards,

Li xing
