- In response to your request for evaluations of the existing cyber 170 series
- kermits, we have installed both kermits at this site (running cdc 855 and 990 m
- machines). The fortran kermit (from UT) is specific to their system in
- many ways because they run a homebrew operating system (taurus) instead of
- NOS. this even has a unique character set, posing formidable conversion tasks.
- it was done here, but the results were not impressive - inefficient in speed,
- occasional bugs. A systems programmer wrote a kermit for local use in CDC
- CYBIL (a high level systems programming language) but it is bug-ridden and
- of comparable efficiency to UT kermit. If you'd like a copy, he can probably
- be persuaded to part with one - his address on bitnet is CC100td TD at GITVM1.
- Overall, the clear winner is Manchester KERMIT in CDC COMPASS. THis is
- very well written, modular, commented well, and 5 times faster than either of
- the previous CDC kermits. Its only deficiency is requirement of parity
- specification at compile time and inability to do 8-bit transfers without
- quoting. These should be easy enough to add - even without, it is far and
- above the best-designed kermit for CDC equipment. The CYBIL version, after
- appropriate debugging and efficiency enhancement, will prove eventually
- worth supporting, as it will run under NOS/VE without major change, whereas
- the assembly version will be useless.

-
- Concerning your question about multiple Kermit sources for
- CDC Cyber machines, I see the following situation:
- On Cybers, there are now three supported operating systems:
- NOS, NOS/BE (both stone age) and NOS/VE (new,virtual memory).
- The old Fortran Source you have is supposed to support both
- old operating systems. (I also developed a derivative that
- runs under NOS/VE, which I will send shortly, but everyone
- expects a new OS Revision, which I expect to be incompatible
- in critical areas, so I'll wait a few weeks. (. And then are
- those bugs .) )
- The new (COMPASS) source only supports NOS, and this is not
- easy to change in an assembler program.
- In the area of functionality the Compass program is better, as
- it supports compression and 8-bit quoting. It also has a better
- throughput rate, as it is a very small program that can be
- swapped fast.
- To add to these complications I hear that there is a Kermit
- under development at Imperial College London (?)
- that is supposed to be written in Pascal.
- Furthermore, under the new NOS/VE is a UNIX subsystem available
- called VX/VE, that runs C-Kermit with 3 small mods (sys3 version).
- On all these themes, there has been a discussion on the Cyber-L
- distribution list (I could forward the relevant entries). A further
- point was the host of local mods against the distributed Fortran
- version that need to be consolidated.
- Finally, what is really needed for Cyber systems is a long packet
- or window version of Kermit, as Cybers are notoriously slow in
- forwarding information through front-ends and operating system
- layers. This is not yet available in any of the listed versions ...
-
- (Shoul I have sent this to the list or to your address ?)

- Dear Dr Phillips,
-
- I am writing in response to the question about multiple versions of
- Kermit in your newsletter number 90. Please forward this information
- to Columbia.
-
- I am the author of the COMPASS version of Kermit. The reason I wrote
- it was that neither we nor any of the three other CDC sites with whom
- we are in closest contact were able to make the UT Kermit run on our
- machines. Because Kermit needs to interface so closely with the
- operating system, and in this case because it needs to bypass ordinary
- I/O to gain 'robustness', I chose to write it in COMPASS, the CDC
- assembler language for all of their 60-bit mainframes. This makes it
- less portable in a sense, but the UT Kermit, despite being written
- partially in FORTRAN and partly in COMPASS, is restricted not only
- to CDC machines but even, it appears, only to those which use certain
- modifications to the operating system developed in Texas and Arizona.
-
- Yours,
- A. V. Le Blanc
