- Ummm, since when have DL11s had settable baud rates? All the ones I've
- seen have required fiddling with DIPs or wirewrapping jumpers. SET
- SPEED=TTn:xxxx doesn't work for DL11 devices, and it's probably a bug
- that setting the speed from Kermit doesn't give an error message to that
- effect.
-
- Try configuring the device to the correct speed, use SET LINE and go for
- it.
-
- NB: a DL11 (or compat) is very very dumb and only has a single character
- buffer. Using it for outgoing modem access at any kind of speed will
- probably result in lost characters. An 11/34A with DL11s under RSX-11M
- V4.1 couldn't cope at 2400; sticking the modem on a DZ11 port fixed the
- problem, due to the silo buffer on the DZ11.
-
- Kermit definitely worked for me under the above setup (on the DZ11 and
- DL11, apart from the odd lost character when on the DL11).
