Hello everyone,

I'm using an Ethernet/232 converter which communicates between IOC and the RS232 device , and specify the Internet host and port numper like :

drvAsynIPPortConfigure("L0","192.168.0.21:1",0,0,0). Then running the application, it occurs:

  [fel@fel iocPSM6003]$ ../../bin/linux-x86/PSM6003 st.cmd

#!../../bin/linux-x86/PSM6003

## You may have to change PSM6003 to something else

## everywhere it appears in this file

##< envPaths

##cd ${TOP}

## Register all support components

dbLoadDatabase("../../dbd/PSM6003.dbd",0,0)

PSM6003_registerRecordDeviceDriver(pdbbase)

## Load record instances

dbLoadRecords("../../db/psm6003.db","user=felHost")

##dbLoadRecords("../../db/psm6003.db","P=PSM6003:,R=,L=0,A=0")

##drvAsynIPPortConfigure("L0","127.0! .0.1",0,0,0)

drvAsynIPPortConfigure("L0","192.168.0.21:1",0,0,0)

##drvAsynSerialPortConfigure("L0","/dev/ttyS0",0,0,0)

##asynSetOption("L0",-1,"baud","9600")

##asynSetOption("L0",-1,"bits","8")

##asynSetOption("L0",-1,"parity","none")

##asynSetOption("L0",-1,"stop","1")

##asynSetOption("L0",-1,"clocal","Y")

##asynSetOption("L0",-1,"crtscts","N")

##asynOctetSetInputEos("L0",-1,"\n")

##asynOctetSetOutputEos("L0",-1,"\n")

##cd ${TOP}/iocBoot/${IOC}

So, what probably has caused my problem?

Thanks,
