FW: FW: Old modem list
I have my modems connected to an HP E35 unix system with 8 built-in (sorta)
You will loose your external serial ports anyway. Even if you set your
external ports to COM1 and COM2 and set you internal modems to COM3 and
COM4, COM1 & COM3 will be trying to share IRQ4, and COM2 & COM4 will be
trying to share IRQ 3. You will not be able to use COM1 & COM3 at the same
time. Likewise COM2 & COM4. Although there is nothing in the design of the
IBM PC ISA bus preventing boards from sharing interrupts, the boards would
*have* to be designed with this in mind. Also, the OS and serial port
drivers would have to understand shared interrupts.
Some serial port boards let you choose IRQs other than 3 and 4, but not
many. If you have one of these, you can set your modems to COM1 and COM2
(IRQ 4 & 3) and set your serial port board to COM3 and COM4 *but* with IRQs,
say, 5 & 9. Or perhaps you could find internal modems that allow IRQs other
than 3 or 4.
I have never seen any ISA serial boards designed to share interrupts with
another board. Likewise motherboards with built in serial ports. Likewise
internal modems. Keep in mind that I am talking about sharing interrupts
between ISA boards. There are several serial port boards with multiple UARTS
that share an IRQ - but only on the one board.

You suggest the Supra fax modem?.. I wanted an external since I will have
two modems. I didnt want to use up both serial ports for the external
Are you using a serial port expander?
I agree with your assment of the internal modems!
