I just picked up a ven-tel md212 plus modem (circa 1982).  Unfortunately,
I cannot find any documentation on the thing.  I'm using it with the
PROCOMM terminal emulation package on a PC-clone.

My problem...  The modem is not properly configured for umodem binary data
transfers.  It works for 7 data-bit transfers (even parity I believe), but
I can't figure out how to run 8 data bits, no parity.  I would imagine that
there is some combo of dip switch settings that determine parity, but I have
not been able to stumble onto it.  The modem has two banks of dip switches
(labeled F and H) with 10 switches per bank.

Anyone out there have any information they can share with me on these
modems?  Any help would be greatly appreciated.  Please respond via e-mail,
as I do not normally follow this group.
