Thanks Eric for the suggestions! For the terminator character error message, I get : Set EOS failed: L0 setOutputEos not implemented

when enabling asynOctetSetInputEos("L0",-1,"\n") and asynOctetSetOutputEos("L0",-1,"\n").

Good point about the double cast on atof - there was no reason for it, have removed it. I tried turning on more diagnostics but weirdly enough don't even see any communication with the device in terms of bytes being read or written. However I can see the frequency change on the device so I know that setting the frequency works. Here's the output from the ioc:

cd /home/admx/admxepics/iocs/SdCarLO

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

Set EOS failed: L0 setOutputEos not implemented
