You should definitely setup your comports using different IRQ's ... this
may clear up your current problem and cause you less grief in the future.

Perhaps the following from the Windows Support Asst will help:

...........................

Windows 95 includes a set of "Basic Configurations" for communications
(COM) ports. These configuration options make it easier for you to avoid
hardware conflicts by letting you easily change the settings a COM port
uses.

These Basic Configurations provide the following:

A default configuration for each COM port. You cannot change this default
setting.

 Additional configurations for each port that lets you edit the IRQ
setting. These configurations do not let you change I/O addresses.

 Additional configurations for each port that lets you edit both the IRQ
and the I/O range.

MORE INFORMATION

Basic Configurations are determined by the following table:

Basic
Configuration  IRQ Setting   Editable?  I/O Setting    Editable?	


0               4	         No	    03F8-03FF	No
1               4	         Yes	    03F8-03FF	No
2               3	         No	    02F8-02FF	No
3               3	         Yes	    02F8-02FF	No
4               4	         No	    03E8-03EF	No
5               4	         Yes	    03E8-03EF	No
6               3	         No	    02E8-02EF	No
7               3	         Yes	    02E8-02EF	No
8           Variable        Yes	    Variable	Yes

COM 1 defaults to Basic Configuration 0. The IRQ can be changed by
selecting Basic Configuration 1.

COM 2 defaults to Basic Configuration 2. The IRQ can be changed by
selecting Basic Configuration 3.

COM 3 defaults to Basic Configuration 4. The IRQ can be changed by
selecting Basic Configuration 5.

COM 4 defaults to Basic Configuration 6. The IRQ can be changed by
selecting Basic Configuration 7.

Basic Configuration 8 can be used to configure additional COM ports because
it lets you change the IRQ and the I/O address.

Example
The following is a sample procedure for changing the IRQ for COM 1:

1. Click the Start button on the taskbar.

2. On the Settings menu, click Control Panel, then double-click the System
icon.
	NOTE: You can skip steps 1 and 2 if you use the right (secondary) mouse
button to click the My Computer icon and then click Properties.

3. Click the Device Manager tab, double-click Ports (COM & LPT), then
double-click Communications Port (COM1).

4. Click the Resources tab.
	NOTE: COM 1 defaults to Basic Configuration 0, and the settings are
according to the table above.

5. Click the arrow next to the Setting Based On box, and click Basic
Configuration 1.

6. Under Resource Settings, double-click Interrupt Request (or IRQ), then
click the up or down arrow to change the Value field setting.

7. Click OK and restart Windows when prompted.
