If you know hardware but not linux, take the ISA. If you know linux, take
the PCI. If you don't know either, then take the ISA because you'll get
more experienced help with an ISA.
The ISA modem will be easier to get linux to funtion with it. The PCI
modem will be easier for the motherboard to handle immediately (since BIOS
assigns the IRQ and other resources, and there's very little chance of
conflict - where with an ISA it *is* possible to get IRQ and COM settings
conflicting with the on-board serial ports or other serial devices).
I haven't used the 5687-03, but I own a 5610 (3CP5610) and currently have
it running in linux (it's the only hardware PCI modem that I've ever seen -
surely there are more, though). I paid about $90 for it. In order to get
any hardware PCI modem (without any funky drivers) to function in linux
right now you have to issue a setserial command of the following format:
'/bin/setserial /dev/ttyS2? uart 16550A port 0xb800? irq 9?'
where you determine the correct settings for the items with ? (usually by
looking at /proc/pci). Then typically you'll want to have a symlink from
/dev/modem to /dev/ttyS2?
I have this command as the first line in my /etc/rc.d/rc.sysinit file.
