[arch-general] dialup woes wvdial, external v92 modem connected via usb/serial adapter

[Joe(theWordy)Philbrook]

It would appear that on Jun 4, Ross did say:

I would have thought so to. But unless I'm remembering wrong, isn't
/dev/ttyS[1-3] the linux equivalent of com[1-4]? In which case, if the
modem could be found on one of those wvdial wouldn't tell me:
--> Cannot get information for serial port.
just before it initializes the modem device specified in the
wvdial.conf file, would it??? And in any case, /dev/ttyUSB0 is where
wvdialconf identified my modem.

Wvdial only finds the modem when I specify 'Modem = /dev/ttyUSB0' in
my wvdial.conf file...
