Problems with Compaq 486/C LTEs and Megahertz 14.4k Modems (99254)
This article was previously published under Q99254
SUMMARY
The Megahertz 14.4-kb modems in the new Compaq 486/C LTEs operate
correctly only when in the docking station. When in the expansion
base, they do not respond to any commands during battery or AC adapter
operation, not to any commands from RAS, Windows Terminal or MS-DOS-
based terminal packages, regardless of the power source. They work
properly only when in the docking station.
Originally, this appeared to be related to power conservation, because
CMOS setup showed the modem state as OFF. However, using Powercon from
MS-DOS and setting the modem to ON did not fix the problem.
This is caused by BIOS v1.06--a bad BIOS revision on the modem itself.
BIOS v1.09 CURES the problem.
You can determine the modem's BIOS revision by typing AT %V from a
terminal program.
