yes, I did indeed find numerous Computerworld ads for this unit but
since they were ads, they were kind of light on facts.  From those,
and the little flip-style manual inside the paper compartment, I did
conclude it was capable of 9600bps on the serial interface but I am still
missing any detail on how you choose whether you are talking on that
DB25 or through the internal modem.   I'm guessing there are a couple
pins that get jumpered together when you plug in an external cable but
I don't know that yet for sure.  The flip-manual does not discuss
selecting modem vs external interface.

Thanks for making a terminals-wiki entry for it.  I will certainly feed
back any more info that I come across.
