hello all,

I am designing an IOC for my serial device which is an keithley picoammeter. I am using Linux opensuse and EPICS base 3.14.12.5 and stream device. when I am connecting my device with usb/serial cable it works file. st.cmd for above setup is

#!../../bin/linux-x86_64/K6485

## You may have to change K6485 to something else

## everywhere it appears in this file

epicsEnvSet("P","$(P=K6485:)")

< envPaths

epicsEnvSet("STREAM_PROTOCOL_PATH","${TOP}/db")

cd "${TOP}"

## Register all support components

dbLoadDatabase "dbd/K6485.dbd"

Now I want to connect my device through moxa 5150A board which is a Ethernet to serial converter having default IP address 192.168.127.254 I changed st.cmd and the error log is like --
