Modem properties "Not Functional"
I have been running Win2k for several weeks now (almost a month), and I find
it very stable. However, I am facing a very strange problem related to my modem (A ThunderCom
Sigma-SII V.90 Modem). Previously, I was able to use this modem to connect to the Internet.
Everything was perfect until yesterday when I was downloading a file from the Internet. I was also
trying to watch a VCD using PowerDVD on Win2k. The moment the CD-Rom drive was read, the whole PC
suddenly rebooted. Win2k booted up fine but when I checked my modem properties, it said "Not
Functional" on the right hand column. The modem was turned on the whole time. I even shutdown my PC
and then powered it up with the modem turned on, but it still says "Not Functional." Reinstalling
the drivers did not seem to work as well. I even tried removing the current drivers and then
reinstalling them to no avail. I also tried installing a standard modem driver as well but it does
not work. Is there anyway to fix this besides doing a reinstall? I am currently dual-booting WinMe
and Win2k. In WinMe, the modem works flawlessly.
I am afraid I cannot come up with a slick solution for you. It seems fairly certain that you
corrupted either a file, a Registry entry for TAPI, or the modem interface. I am interested in what
happens if you put a plug-and-play external modem on the serial port and restart. If this modem
also fails to work, then you may be stuck doing a reinstall.
You might want to try the Last Known Good Configuration option to recover a previous Control
Set. Press F8 at boot time and select the option. This would restore portions of the previous
SYSTEM hive in the Registry. If you corrupted the Registry, then this might do the trick.
