In message <199503041004.LAA00324@beverly.rhein.de>, you write:

Yeah, I've seen this happen before. It usually bites me while I'm
trying to do last-minute FTP's of stuff I need to hand in either to
the Sparc [Solaris 2.3] or directly to our QMS printer. I'm always
in too much of a hurry to track it down and generally end up putting
stuff on floppy and being late to class ;-(
I *am* using SLIP 99% of the time, because I've got Mark Weaver's
nifty SLIp program that does all the things I want my PPP to do and
haven't had the time to set up [ie, keeps dialing till it gets a
modem, passes the Cisco my username/passwd,...]

Do you see this regularly enough to say that it's fixed after one try?
For me, this is an on-and-off thing.
