The IBM MWave modem is both a modem and a sound card. The MWave modem has
had many rough spots, and I have heard many times that at one point they were
recalled by IBM, though I have not been able to find any solid evidence yet to
support this claim. The main reason for the supposed recall is that they
have trouble connecting to modems other than other MWaves. The MWave modem
is tricky, and there are different internet sites that are actually dedicated to
getting this modem to work. One of these sites dedicated to solving
problems with the MWave can be found at: http://modems.rosenet.net/pn/ibm.phtml
The modem is sometimes hard to deal with, and some Internet Service Providers
even go so far as to refuse to support customers with these modems.
However, they CAN connect, and hopefully this article will give some insight to
how to get them to do so. Remember, as always, it is HIGHLY
RECOMMENDED that one of the
major steps that you take in getting these modems to connect is to get the
latest software for the modem.
Like the Motorola SM56's, I have yet to find a basic procedure for getting these
modems to work, as I have not dealt with them quite as much as I have certain
other brands. They are tricky, but most connection troubles you experience
with them should be able to be fixed. Also, like the Motorola SM56's these
modems are sensitive to line noise, even though they are not 56k modems.
Remember to be wary of line noise and devices attached to the phone line the
modem is hooked into that could cause line noise, like splitters or surge
protectors. Here is the procedure I would use:
Lower these 1 notch apiece and add an init, if the problems persists try
lowering them all the way.
First lower the port speed to 38400
(No idea, but works! ("H = V.42bis Compression Control))
(Works in the UK...do not know if it works here. Let me know if it does.)
(Connecting to Livingston Portmaster 3's, but worth a try on other units)
(Basic init #2)
(Basic connection trouble solving init)
(Recommended by IBM)
(More of a basic version of the first recommended non-basic init)
(Another suggested init I found laying around)
Other things to try:
If dropped connections are a problem, try checking the box that says required to
connect under error control. If drop connects are not the problem then you
may want to try (as a last ditch effort) turning error control OFF.
Here is where you can get the latest drivers for your MWave modem:
