It should work ok, until you reach the point where you decide to move to
ISDN with an internal card, and wont to configure ppp so it uses the
modem
emulation of the ISDN-adapter for dialing to your ISP, but althoug you
want
to keep your Modem for faxing. now you tell your ppp-setupscript to
change to
for example ttyI5. now this script modifies the link /dev/modem to point
to
ttyI5 and you wonder, why you don't get any faxes anymore.....
that is the problem using /dev/modem with more then one package/program.
ok, you may say this example is very linux-specific, but it shows the
main
problem.
