>Description:
uart cannot identify 3COM PCI FAX/MODEM and misidentifies its chip as
8250.  This is the ONLY internal PCI hardware modem in existence and
has been (and remains) the only choice for an internal dial-up modem.
 None the less uart can manage to connect ppp using tun on boot, but
cannot reconnect on demand.  sio worked and replacing it with something
broken seems a step backwards.
>How-To-Repeat:
Attempt setting up ppp on demand with the internal hardware 3Com PCI
FAX/Modem in any 8.x.
>Fix:
downgrade to 7.x with sio
