Doug, it seems to me that, though you got plenty of "responses," you 
didn't get an answer.

I usually do the line processing after receiving the data, so I usually 
don't do it this way.  Maybe 'until' only matches on the first 
character.  I don't get that impression from the TD (list jargon for 
Transcript Dictionary), though.

If you are doing a repeat for each line or referring to 'line n of' you 
will not get the LF.

The function below takes a string and converts it to hex.  You can use 
it to dump your line in testing.  For example "abc" & crlf will be 
translated to "6162630D0A".  Look for 0D for CR and 0A for LF.

function hex s
  get binaryDecode("H*",s,h)
  return h
end hex
