You want a DOS driver for the Conexant D480? Boy you're lucky if you can find one. There are very few DOS drivers for V92 modems if none.

I use a soft DOS equivalent Hyperterminal or Procom
I use script in this soft
Usualy i have no problem with com1 with external modem on different PC
but laptop Dell use internal modem, Conexant use com3 IRQ5

i want values for irq and mask in Hexa

If not exist information for this configuration , i use external modem...

thank for your help

COM3 is usually 3E8 but can't help you with the others...

COM ports 3 and 4 are defined in DOS but are co-users of the IRQs used by 1 & 2 and addressed, If I recall correctly as 2E8 and 3E8 (as noted by Roger).

From the description you are probably using a PCI modem that is really sitting in the higher IRQ area and being mapped to a lower location by the operating system to fit the requirements of the operating system communications environments. Plug and Play has that ability. DOS does not.

I am not aware of any DOS based communications programs written for these types of modems.
