Comm Port Problems with Win98

[Guest_imported]

We have a problem using Com 1&2 with external modems with some mother boards using Windows 98 and we can not figure it out. If we boot up with DOS 6.2 the program will initialize the modem and it will work, however using the same mother board, once in Win98 it can't find the modem. Even if we restart window in DOS mode it still doesn't find the modem. Does any one know why? Also, does anyone know's if using Silver Clip can I work with a PCI modem or an AMR modem, if so what brand do you recommand?

Thanks a bounch.

Power saving! Windows 98 starts up and the com ports are switched on. It save this info, loads Windows and the power saving turns the ports off. You load a DOS app and Windows returns the origional status, ie port is on, while in fact it's off.

You could turn power saving off in the BIOS, but this can allow AMD Athlons/Durons to run hotter, ACPI issues a stop on the CPU rather than a pause in an idle state and this can cool the CPU by 3-4Deg C.

There is a registry hack:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\VCOMM change it from 01 00 00 00 to 00 00 00 00

Reboot the PC and things should be OK
