OKAY.. I have this same plotter up in my attic, and had a heck of a time getting it to work.. the secret is the NULL modem cable part.. I standard serial cable will *NOT* work.. you need a NULL MODEM adapter to put on it.. this reverses pins 2 & 3, and maybe some others.. it basically reverses all the send & recieve wires.
You will probably have to search a junk parts bin at a computer store, or find a *KNOWLEDGEABLE* person in a computer store to help you find one.. try to finda computer tech who has been in the field for 10-15 years.. he will rememebr the olden days when these items were standard!
Mention BBS's to him, and hear him talk about the glory days back then.. hahaha
