Ya, I reversed a product that had a big 24 (28?) pin 202 modem from OKI, and
when I went to get some for my product, I couldn't get any cooperation from
OKI on literature or data.  I see MX-COM has some solutions, but the closest
one was some sort of synchronous solution, where the data must have a
pre-amble of some sort.  Really threw my plan for plain old asynch 8/1/none
plan.

I take the other fellow's point on the caller ID recieve only, that is a fine
idea.  Sending should be no big deal, as he mentioned.  I'll look into that.

Thanks all..
