Hi all. I need some help in buying a new modem. Basically what I need to know is whether MNP error protection circuitry is worth the extra money for a 2400 baud modem. Is it? Thanks for the help!

I would suggest that whether or not you need the extra protection depends on the quality of the phone line you are using. Also, some cheaper modems are more susceptable to line noise than most, but if you are buying a popular brand of modem, such as a Hayes, Avatex, U.S. Robotics, or Telebit, I would not worry about it. I have an Avatex 2400 baud modem without MNP, and I very rarely have any problems with line noise. I have also used Zoom Telephonics and Practical Peripherals brand 2400 baud modems without MNP and had no noise problems. In fact, the only 2400 baud modem I have seen that was below standard was an Omnidyne, but it had been dropped off a table onto the floor a few times. In theory, MNP can also result in slightly higher data transmission rates by utilizing data compression techniques, however this is only useful if you plan on doing large file transfers over the phone, such as if you plan to call a lot of bulletin boards. One problem with MNP modems is that you only gain the advantages of MNP if you are calling another modem with MNP, and I am almost positive that the modems WPI has do not support MNP. In summary, I would get the MNP if I had a noisy phone line and/or I planned on doing lots of file transfers with bulletin boards that have MNP modems, otherwise, I would save my money.
