- Subject : PERQ KERMIT bugs
-
- Dear Frank,
-
- I'm catching up here on a year of saved up messages for you! Below are
- some changes and bug notes on the PERQ KERMIT (PQ) sent by Ian Clifton
- of Daresbury Laboratories.

- Alan Phillips
- Lancaster University
-
- ---------------------------------------------------------------------------
-
- 1) In KermitGlobals.Pas, a couple of identifiers, "EscapeChr" and
- "DstryCmdFile" needed to be changed to "EscapeChar" & "DstryCmdFiles" to match
- the rest of the program.
-
- 2) There is a module "Sleep" which I guess is part of some versions of
- Perq Operating System. PQ-Kermit seems to work with all references
- to this module ( & also "Nap" which is presumably part of it) commented out.
-
- 3) There were a couple of bugs in the way PQ-Kermit handles the setting-up
- of the control character quote (See Section 7, "Initial Connection" of the
- Protocol manual.
- i) PQ-Kermit compares the QCTL slot [of the data field of the ACK to
- a Send-Init] to 0 when it should compare with ASCII(blank).
- ii) PQ-Kermit also applies control-chatacter prefix decoding [to the ACK of a
- Send-Init] when it shouldn't. So when a remote Kermit sends a "#" in the QCTL
- slot of it`s ACK to PQ-Kermit`s Send-Init, this character & the one following
- are decoded as a single control char! I added al extra Boolean global variable
- to PQ-Kermit so that the relevant parts of the program can switch prefix
- decoding off temporarily.
