DECcomm Version 5.01 Release Notes
----------------------------------
This version of DECCOMM implements nearly complete support for
the Revision 5 FOSSIL specification. Opus 1.10 and
BinkleyTerm 2.00 use extended Rev 5 features to get more speed
on fast modems. (And in the case of Binkley 2.00, the
external function support is used for Video FOSSIL!)
To my knowledge, the only significant omission from this
driver is the lack of support for XON/XOFF as a restraint
mechanism on the Receive side. There are probably a few minor
nuances that I will have to address, but by and large, DECCOMM
is compliant with the Revision 5 specification. This includes
support for 5, 6, 7, and 8 data bits; odd, even and no
parity; 1 or 2 stop bits; and support for BREAK
transmission.
This version of DECcomm therefore differs from Rev 3 in some
minor respects, and if you are using Ron Bemis' OUTER program
(or CALLTIME) you should contact him about getting a new
version.
ALSO -- unlike prior releases of DECcomm, this one actually
snags the serial interrupt rather than using MS-DOS calls.
This was for purposes of speed, and the gain was significant.
But this means that you can't do all the things with Opus or
whatever active, that you used to (like using LC-Term). You
also should explore the FOSLAUX driver as an option for some
of your AUX port stuff. Of course there's always BinkleyTerm
as a simple terminal package.
Now the good news. If you have been thinking about buying a
fast modem but ... "why bother, the Rainbow isn't fast enough
to drive it!", I have some interesting information for you.
Opus 1.10 can drive a Telebit at about 1400 CPS on a Rainbow
with this driver. With maximum compression on a USR HST,
BinkleyTerm 2.00 is getting 1885 CPS. So if you are spending a
lot of time transferring data you might explore high-speed
modems.
