- In answer to your questions, MNP is a hardware-based error-correcting
- protocol. You really don't have to worry about MNP error correction if
- the modem has V.32/bis ability which most do these days. The 16550 UART is
- just a new way of describing the serial-type connections made to your
- computer. It's not a big deal because most machines made now have this.
- Group III is the standard fax protocol for fax machines all around the world.
- Occasionally, machines use G3 F which is a fine mode that makes finer print,
- but you won't see most people using that because it requires more time.
-
- Brand names? Zoom makes a decent modem, but of course, it's name brand, so
- I assume that it costs a bit more than the rest. I've also heard of Infotel
- who also puts out a decent modem. The only company that I dare knock is
- Lightning Comm. Sure their modems are cheap, but take it from someone who
- ordered one of their modems and then returned it, it's a piece of #$%^. Nothing
- else said.
-
- Some advice is to make sure that you get one that can handle V.32, V.32bis,
- V.42, V.42bis. These hardware high speed protocols are taking over the HST
- market that US Robotics has so arduously maintained. At least you're not
- shelling out $700+ for a USR Dual Standard...Hey, it's compatible with
- everything, but you're also spending QUITE a chunk of money.
