Sounds to me like you need to install your new modem on COM3. (change the driver setting)

Try to check whether there is init-string for the modem.  If yes, it may cause that error if the string is wrong.  Try to remove the string and see what happens.

Removing the init settings has not helped.

I ran a modem test. It tests out okay except occasionally coming out with the answer that interrupts were not generated. However, the com ports and IRQ settings seem okay.
Any ideas?
