Gents, thanks for your work on the GTP. I have a [silly] question, IMO not clear in the protocol draft.
Blank lines are specified to be ignored. But what should an engine do with a line containing an Id, and nothing else?
If this counts too as a blank line, then the sender gets no acknowledge for some Id number.
If, on the other hand, a response =Id should be issued, then this is inconsistent with the treatment of blank lines, which get no response.
Thanks, Salvador
