- Subject: Getting Kermit to work on Acorn Cambridge Workstation
-
- In reply to Dudley Long's query, yes, it does work at least on an Acorn
- Cambridge Coprocessor, although attempts to change the line speed from within
- kermit do not seem to work. However, the speed can be changed with *fx calls
- before kermit is entered, and that seems to work.
-
- We are actually running a version that we got on disc, which omits the files
- ACKERM.DOC and ACKERM.HLP that are online at Lancaster. The latter is the
- release notice, which contains a brief description of which source file does
- what, and so is of some minor use. (However, I hope that there are less errors
- in the source files than there are in ACKERM.HLP!) ACKERM.DOC is just an
- identical (as far as I can see) copy of the Unix C-Kermit manual, with no
- description of the peculiarities of Panos-Kermit, so I wasted my time pulling
- it from Lancs!
-
- [Ed. Actually, ACKERM.DOC is just a copy of the C-Kermit manual that I added to
- the files. I don't have any Panos-specific documentation at all - if anyone has
- some on a machine, please mail it in and I'll it to the files. ACKERM.HLP is my
- typing in of the release notes that Acorn sent me. Any typographical errors are
- my fault!]

- There's a pernicious bug in Acorn's version of C-Kermit for the ACW443.
- This prevents baud-rate changes from being obeyed when the poor unsuspecting
- user goes into connect mode (to set up a remote server Kermit), but only
- when ACW Kermit (attempts to) start file transactions. This is most
- confusing, especially to first-time Kermiteers ...
- The bug fix is to re-instate some missing code from conect() in
- ckpcon-c (alias acpcon.c), which appears to have been rewritten from
- scratch. Herewith the context diffs:

- Apologies for holding back on this ... I haven't even got round to that
