Hi folks,

I feel like I'm close to getting EPICS to talk to our Keysight measurement mainframes but can't quite get there.  I don't see any errors when I start the IOC with st.cmd until after iocRun, at which point it reports : 
2023/01/20 11:08:24.866492 LAN0 swag5testIDN: No reply within 1000 ms to "*IDN?"
2023/01/20 11:08:25.869293 LAN0 swag5testIDNwf: No reply within 1000 ms to "*IDN?"

How do I get some more debugging messages?  Maybe some capture of what it's sending?  I think it's getting no response because asynReport 10 LAN0 shows:

LAN0 multiDevice:No canBlock:Yes autoConnect:Yes
    enabled:Yes connected:Yes numberConnects 1
    nDevices 0 nQueued 0 blocked:No
    asynManagerLock:No synchronousLock:No

I also did a basic test using telnet and got a reasonable response.  Below I've added the output from running st.cmd.
