Hi Benjamin,

It should work with a StreamDevice protocol like this:

getData {
  maxInput=8;
  in 0x20 0x21 "%#2r%(\$1)#2r" 0x17 0x18;
}

record (ai, "$(P)Data1") {
  field (DTYP, "stream")
  field (INP, "@$(PROTOCOLFILE) getData($(P)Data2) $(ASYNPORT)")
  field (SCAN, "I/O Intr")
}

record (ai, "$(P)Data2") {
}

Hello,

I am having a device that does continuously send data via serial port in the form 20h21h<lowbyte1><highbyte1><lowbyte2><highbyte2>17h18h. In a rate of ~ 10 Hz. I guess one can get the two integers by using stream device and use a calc record to combine the low and high bytes. But stream device does not seem to be appropriate here. Are there any other suggestion?

Thanks a lot, Benjamin
