just some thoughts, suggestions and mental mastication follows...
If you can not chase this down, and if running scanreg does not find any problems with your modem or communications. Your dialup TCP/IP adapter/Modem settings are correct and your TCP/IP (protocol bound to the adapter/Modem) is configured correctly. Win2k SP3 or Win XP's personal Firewall is not enabled. Or there are not any residual files from your firewall still loading up for any odd reason the uninstall might have missed them.
you might want to go into Hyperterm and make sure nothing has changed you disconnect string or any other modem arg's (S registers)....
if nothing else works...
load Hyperterm so it initializes the modem and in the connection windows type and do the following to the factory default stored eprom settings :
type the string as show directly below and a discription of what it does is below that.
AT &F &C1 &D2 S10=55 &W
----------------------------------------
AT wakes the modem up for input
&F sets it to the default factory initialization string
&C1 sets to data carrier detect (auto sense connection speed, fall back/forward)
&D2 determines how modem uses DTR (Data Terminal Ready)
S10=55 sets the timeout value higer so your modem does not assume a dropped connection whith slow traffic
&W writes the string to the eprom so you do not have to constantly do it manually...
