Thanks for that - it's good to have that in the trivia file. Since
I've written code to interface to FTIRs I'm interested in that kinda
stuff.

Onto your need for a solution....

1) You have a lot you can use now. Since one of the other postings
gave you an impressive list of options for looking into serial port
programming and testing (on the nearly 1 year anniversary of it being
on this list) 
2) You've named your board as a TS-7800 which I don't have, I'll leave
you to the capable discretion of others on this list. Someone may
follow up on your AM# question.

Glad to help. Sounds like you've gained some understanding from the
direction I was looking to take you in all this.

Best wishes,
