If you are electrically inclined enough (like me ;>) then you can change
the I RQs around and have very satisfying results. I have 4 COM ports,
COM1, COM2, COM3, and COM4 with IRQs 4, 3, 5, and 9, respectively. You
could also change COM4 IRQ9 to COM4 IRQ7, which is also a good idea. This
has to be done hardware wise on the serial/parallel card in your computer
though with jumpers or switches. This is not a software operation and if
that is what you intend to do, I suggest the method shown underneath.

: Don't change the IRQ of the COM port. This can lead to future problems.
: Are you using Win95? It sounds like you are. Anyways, the fix is the
same
: with Win 3.x and Win95. I have 3 COM ports, one for the mouse, one for
the
: modem, and one for the Graph-Link. Remember that COM1 and COM3 share the
: same IRQ and COM2 and COM4 share the same IRQ. This sequence keeps
: increasing, so odd numbered COM ports have the same IRQ and even numbered
: have the same IRQ. Follow? What you must do is put the Graph-Link on a
: COM port that will not use an IRQ of another COM port at the same time.
: For example, if your mouse is connected to COM1, don't plug the
Graph-Link
: into COM3. If you have an internal modem, try jumpering it for COM3 or
: higher. This can eliminate conflicts with COM1 and COM2 which come
: standard with most IDE controllers. The solution for my setup is to have
: the Graph-Link on COM1, mouse on COM2, and modem on COM3. I will never
use
: the modem and Graph-Link at the same time, so no conflicts. Plus, the
: mouse is on COM2 so I can use it all the time.
