Hi
I just want to clarify a few things about modems. In this instance
please note that I am talking as teh author of the PPP-HOWTO and not as
any sort of spokesperson for Red Hat.
1) Winmodems: these will at best work at 9,600 baud on Linux - if at
all. Avoid at all costs.
2) PnP (internal) modems: many of these will work with Linux after some
jiggling.
If they have a jumper that disables plug and play and allows them to
be locked to a particular IRQ and I/O address, they should work just
fine.
If you use the PnP tool set for Linux (isapnp), many PnP modems can
be made to work just fine - but some won't work at all. This is due
to the fact that the PnP spec is somewhat broken and hence its
implementation varies...
Even for PnP modems that you cannot configure with isapnp, they can
frequently be made to work by booting into Windows and then warm
booting to Linux.
3) Internal vs external modems: with the info given above as a proviso,
there is basically no difference between internal and external
modems.
I prefer to use external modems as I can see what is going on more
clearly. In addition, if there is a problem on the modem (such as a
lightning strike on the phone line), having it outside the computer
means that it may just NOT blow the computer...
