I want to install a 56k data/fax/voice modem to replace my data/fax modem. My inital question was while I'm looking at all these descriptions what will it say if it just needs a phone line hook up? I was looking for a PCI but now that I've read all these posts - would USB or serial be better? I have Windows 98SE in a HP with 433 mhz Intel Celeron. Take it easy fellas - I'm new to this game.
