Well, this one has me baffled. I'm trying to set up a UUCP connection from a site in the UK to one of my machines in the USA. The UK machine is a Sun SLC running SunOS 4.1.1revB, the USA machine is a Sun 3/160 running SunOS 3.5. The SLC is polling the 3/160. The SLC is connected to a Hexacom modem (about which I know little or nothing) and the 3/160 is connected to a Telebit TB+. I'm trying to make a connection at 2400 baud, at MNP4. When I initiate the poll (with debugging level set to 9), I see that the SLC places the call correctly (it works through the chat script and the connection succeeds). However, at the point that the remote uucico kicks in, things start to go awry. The remote uucico responds with a "Shere" message, to which the local uucico responds with "Smyname -x9". At this point, I see no more messages passed between the two uucico processes. It appears that the remote uucico times out, and the remote system redisplays the login prompt, at which point the local uucico decides that the call failed, and exits with an exit code of 101 (whatever that means). I know (well, I strongly believe :^) that the 3/160 end of things is set up correctly. That machine is regularly polled by other machines in the same way as this SLC is trying to. However, all of the currently operational connections have Telebits at both ends. The UUCP config files (Devices, Dialers, Permissions, and Systems) are the same as those of one of my working connections with the exception of the differences necessitated by the Hexacom modem... e.g. the connection sequence in the Dialers file, and the device name/speed in the Devices and Systems files. In any case, the modem-specific part of the connection appears to be occuring successfully. Does anyone have any ideas about what's going on here? Could it be a modem problem? Something to do with MNP (none of my other connections use it)? Something to do with the intercontinental phone line? Lacking any answers, does anyone have any constructive suggestions for how I go about debugging this problem further? Followups have been directed to comp.dcom.modems. Thanks in advance. --dave -- David W. Minnich INTERNET: dwm@fibercom.com FiberCom, Inc. UUCP: ...!uunet!fibercom!dwm P.O.
