Windows98-Bios

Here is my dilemna

We have Windows98 on Laptops using PCMCIA cards for Modem connections.
We use DOS shell to communicate to the Modems. Unfortunately when the DOS shell is open and we run utilities like UARTID or COMTEST, the program are not able to access COM3, COM4 etc. The reason being most of these programs look at the BIOS to find a entry for the COM ports.
Is there a way to make WIN98 make entries of COM3 and COM4 in the BIOS and is there some new drivers or documentation which allows me to access the COM ports directly even if there are not entered in the BIOS.

Appreciate all the help.

Win often freezes up COM ports, thus disabling its use at DOS level. Edit file \WINDOWS\SYSTEM.INI and add these two lines at the section named "[386enh]":

      COM3AUTOASSIGN=2
      COM4AUTOASSIGN=2

That makes Win frees COM ports to be used freely from DOS applications.

I hope this be the answer you need.
