Dear All

I want to send and receive data at port. I am successfully sending the data and verified it but I can't receive the data from the port. Please check the problem and suggest me how to correct it. I have attached my database file. My st.cmd file is:

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

## You may have to change serialTest to something else
## everywhere it appears in this file

< envPaths

cd ${TOP}

## Register all support components
dbLoadDatabase "dbd/serialTest.dbd"
serialTest_registerRecordDeviceDriver pdbbase
drvAsynIPPortConfigure("L0","localhost:5011",0,0,0)

## Load record instances
#dbLoadRecords("db/xxx.db","user=tasaddaqHost")

dbLoadRecords("db/asynRecord.db","P=a:,R=b,PORT=L0, ADDR=0,TIMEOUT=1,IMAX=100,OMAX=100")
dbLoadRecords("db/serialTest.db","PORT=L0,R=b,ADDR=0,TIMEOUT=1")
#asynOctetSetInputEos("L0",0,"\n")
#asynOctetSetOutputEos("L0",0,"\n")

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

## Start any sequence programs
#seq sncxxx,"user=tasaddaqHost"
