- I am trying to connect a "downstream" site who is using Waffle 1.65
- under DOS 5 without FOSSIL drivers. He has both a Netcomm E7 and a
- Maestro V.32 modem, although these model identifiers may not mean
- much outside of Australia. The whole thing is running on a 486/33.
-
- We have no problem getting our modems to connect.
-
- His problem is that uucico reports carrier loss while his modem shows
- the DCD signal is still high. Initially, his uucico was failing to
- login because it wouldn't receive my login prompt - his trace reported
- loss of carrier instead. As a last resort, he removed the \m parameter
- from his scripts file. Now, he can (blindly) log in but does not respond
- to my "Shere" message - again his trace reports loss of carrier instead.
- We cannot see how to turn off uucico's carrier detection once a connection
- is established. Nor do we want to, really!
-
- We have run up a hefty phone bill trying every combination of init strings
- we could think of, for each of his two modems. The same behaviour results
- for all reasonable combinations, including both &C0 and &C1. &C0 SHOULD tell
- the modem to keep DCD up, no matter what happens.
-
- Now, the REALLY strange thing is that connections using both Procomm (login
- to an interactive acount) and UUPC/extended (to a uucico shell) were simple
- and painless. He doesn't want to stay with UUPC because of its relatively
- poor news support, plus he's attracted to Helldiver as a user agent.
-
- I've asked him to check out his cable to make sure that DCD is propagated
- reliably (no loose pins), but that sounds a bit feeble when UUPC and Procomm
- don't seem to have any problem. I also suggested that he might have configured
- those other programs to ignore hardware DCD - but I doubt that is even possible
- with UUPC.
-
- SO. Has anyone seen anything like this before? Has anyone got any suggestions?
- Are there any neat debugging tricks we should be trying? Would anyone care to
- speculate why UUPC/extended behaves differently? We've run out of ideas, except
- for the unlikely theory that he has a hardware fault.
-
- All assistance gratefully received...
