Problems accessing Com ports from DOS in Win 98 by Bozz
Posted: 30 Jun 02 (Edited 1 Jul 02)

Windows 98 boots up and the com ports are switched on. It saves this info then loads Windows and the power saving turns the ports off. You then 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 cause AMD Athlons/Durons to run hotter, ACPI issues a stop on the CPU rather than a pause in the 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
