External modem suddenly not working (USR V.Everything)

[Travis Troyer]

I have a US Robotics V.Everything external modem connected to 
my system running FreeBSD 5.1 stable.  I got my ppp.conf and 
ppp.linkup files setup properly, and was able to dial-up to 
my provider many times.  I was connected when I accidentally 
knocked the power supply out of the wall socket, and lost my 
connection.  I plugged it back in, turned it off and back on, 
and tried to connect, without success.  So, I rebooted, with 
no success.  I tried shutting down both the modem and the 
system and cold-booting; still no go.  The modem connects 
fine under Windows (dual-boot), but refuses to even dial in 
FreeBSD. 

Any suggestions?

Thanks,
