The port seems to work well on a straight connection, that is, data came in
well with no losses or anything when getting menus, etc from the BBS.  XModem
D/L's using XYDown came in error-free.  "rz" was the only one that balked.

I don't really have any docs as to the flow control setup.  I was using STerm
and I understand that it maybe does its own thing re: flow control, and this
could be the problem.  I suspect that the driver could have something to do
with it.  I believe that the primary design of the ports on this machine is for
terminal support, and some of the lines may not be handled in a manner that
would be best for modem comm.  I can get an internal modem for it, and will
probably go this route.  I was just curious as to why "rz" would not work @
9600 and would @ 4800.  I think I mentioned it, but when the first timeout
came, then a series of 10? - 15? (not sure) timeouts would come at a rate of
maybe 1 per second give or take.  There would be a rapid alternation between
the RD and SD lights on the modem, switching back and forth, seeming to me it
was "RD" in the lead.  Could be a bug on the BBS where if one timeout is
encountered, it keeps repeating timeout error.  I think this because I tried
"rz" with Delphi and although getting several timeouts, the d/l finally came
through (also got some CRC errors even though I had error correction).

While I have you, got a question.  I will be getting "ix" for the OSK system
soon as I get my order in, have coco version and was curious if the ".msg"
files would happen to be compatible.  I suspect maybe not, as some of the
variables are of different size on the 2 systems, but if so, it would be a big
plus.

Well, thanks, TTYL...
