About 3 months ago I upgraded the Mwave DSP in my IBM ThinkPad 760CD (P120, 40MB RAM, 1.12GB HD) with the new driver v2.25 (for windows95) from IBM, which enables 33.6kbps modem speed. The previos version (2.24) has a 28.8kbps maximum. Firstly, whilst on-line at the 33.6kbps speed setting, all sound functions are disabled - irritating when trying to listen to web radio broadcasts!This is a known and documented in the release notes. Is there a work-around, or any plans of a fix/upgrade in the near future? Second and more importantly, occasionally, whilst online, suddenly there is modem inactivity and I get a message informing of an Mwave internal error, then the system hangs, requiring me to press ctrl-alt-del followed by shutting down the program 'discrim', thereafter the system works fine although the modem will not function unless I reboot. Rebooting solves this everytime. As I say, this doesn't happen often and doesn't bother me too much, but it'd be nice to know what's going on. These are the details: "MWAVE 0001: Mwave modem internal Error File: MWMSPCFC.C Line 1857" After clicking 'OK', this is followed by system freeze. On pressing ctrl-alt-del, I find the program DISCRIM not responding, so I shut that particular program down. This follows by another message: "MWAVE 0001: Mwave modem internal error Primary code: 2(0*0002) Secondary code: 4(0*0004) File: MWMSPCFC.C Line: 1580" After clicking 'OK', I get another message: "MMTASK. This program has performed an illegal operation and will be shutdown. If problems persist contact the program vendor." Details: "MMTASK caused a general page fault in module USER.EXE..." After clicking 'CLOSE' on the above dialogue box, all is apparently back to normal - except Mwave modem doesn't work unless I reboot. After shutting down and performing a Test (from the Easy Setup), every components (including the test for the DSP) pass the test. This is consistent and, as I said earlier, only happened once every few days since I upgraded from v2.24 to v2.25 A few weeks ago, I installed Microsoft Internet Explorer 4.0 (release version) with the new active desktop. I started having lots of problems - plenty of crashes, including those similar to the above. So, I decided to clean-up my system by formatting the hard disk and start over - a long and laborious process. I left the Mwave modem setting at the default 28.8kbps maximum (not the 33.6kbps maximum, which will disable sound function whilst online). Now, I regularly (1 in 3 to 1 in 5 times) have problems with the Mwave modem. As before, suddenly there is online inactivity during downloading data (e.g. loading a Web pade or downloading a list of uselet messages), followed by a crash. Each time, at least a copy of IE4.0 and 1copy of Forte Agent are open. I can usually recover from such a crash by shutting down (after ctrl-alt-del) one (or both - depending on which is unresponsive) of the following: 'iexplore', 'explorer'. The result is that I am no longer online, although the Mwave modem seems to think that I'm still online! There is no way to get modem functionality again unless I reboot. Interestingly, this time, there are only very occasionally the Mwave internal error message. Although, I sometimes get the additional Error 201 after rebooting (before Win95 loads), which prompted me to Test the system (via Easy setup) - all tests were passes at each and every instance and rebooting is always possible thereafter. If anyone can shed light on this, I'd be most grateful. I have asked IBM's tech support who were very curteous, yet ultimately unhelpful. I also asked around on usenet. The general advice is that I should wait for a new driver to be released - is there anything on the way? I've waited over 3 moths already. Alternatively, I should revert back to version 2.24. I have resisted doing this previously since I wanted the 33.6kbps connectivity. However, today, since I'm now on 28.8 max setting anyway, I thought I would give the old version a go to see once and for all if this is Mwave problem or a problem with soemthing else on my system. I am glad to report that for the past day (consisting of 4 half-hour to 2 hour online sessions), under similar conditions as before, I've had no symptoms as described above *at all*. So, it really does appear as though it is the driver (v2.25) which is causing th problems. Anyone from IBM out there to comment? Any comments at all, especially (but certainly not exclusively) those with similar experiences, would be most appreciated. Nick P.S. Sorry for the long-winded posting - this message also serves a mental therapeutic purpose - this Mwave thing has driven me crazy!:).
