FWIM and IIRC, X.29 was the standard that describes how an X.25 async

Just googling around, so apologies if I'm way
off, but is it like
this http://benjeapes.blogspot.com/2010/06/back-when-pad-didnt-
even-mean-pad.html ? Is it a serial sniffer? If so and assuming
you know which serial input and standard it's using you could
probably either hook up another serial sniffer/analyzer to it and
see what it's doing or a standard terminal would likely spit
something out once you figure out the proper communication
settings. Given no clue if it's DTE or DCE.
Its a X25 Packet/Assembler/Dissasembler. It allows ordinary Async
Terminals to be connected to an X.25 network. In the UK all
Universities had such networks under the umbrella of JANET. Some at
Janet probably has a manual. I have forgotten almost every thing I
know about them. I have asked one of my former colleagues if he has
any info.
