- 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.
