Have you not been reading this newsgroup recently?  You can't do UUCP out
of a LAT port because for some reason LAT ports were designed without
modem signals on the Ultrix side.  If you can open the port to get to the
modem, that's all the info you're going to get about the connection. 

UUCP depends on modem signals to detect carrier; the only reason UUCP
gets as far as it does is because the Ultrix programmer who modified it
didn't check the return calls from the ioctl()s he added that set modem
control and wait for carrier.  Those ioctl() calls fail, and UUCP
silently barges on to send UUCP data into an uncomprehending Telebit.

You're hosed.  I'm hosed too.  I moved my Telebit to a MVII serial card.
It works fine there.  If I get ambitious, I may pull out the TK70 tape
drive and put the serial card in my own 5400.  Oh heavy sigh.
