- I should have included a little more information, sorry. The modem is a
- Cardinal 9600 (v.32, v.42, v.42bis; not MNP5). I'm running a Mega STE, Tos
- 2.05, with Serial Fix v1.1 in the Auto folder.
-
- Our computer centre says their only supported protocol on the high speed
- lines is 7 bits, even parity. For what it's worth, my configuration in
- STalker is 7 bits, 1 stop bit, Parity 0 (Space). When I use Uniterm I find
- I need 8-1-none.
-
- I've tried Zmodem again, with the -e switch; no improvement unfortunately.
- I've also tried Kermit with the packet length set to 2048 (seems to be the
- maximum accepted by the remote kermit) and *no* flow control. The file
- still comes through with no errors, but at about the same rate as
- previously, around 230 - 240 cps.
