Thanks for the response. Sorry about my long delayed response. I
worked most of Saturday playing around with ppp and various options in
rc.conf trying to narrow the problem down to some kind of route
problem. In the process I did find some routing problems and fixed
them. 

But there was no improvement in the failure to keep an rsh or
ftp session going over a serial port connection with my isp.

I am going to start another thread under the title ``sio problems?''
and try to figure out what's wrong with my serial port. I suspect
while sio4 works enough to start a link with my isp, it somehow
fails at some point. I think the problem is the serial port
configuration. I suspect the swap during bootup sio0 -> sio4 is the
heart of the problem.

With that in mind, I think you are right about a routing problem in
the sense that the mapping of physical serial device (modem) to its
virtual serial device (sio0 -> sio4) is mixed up somehow and that in
turn creats the effect of a routing problem. 

Even if a fixed serial port system doesn't help, at least it will be
one more problem fixed.
