I didnt say MSD wouldnt show someting on COM3, COM1 or any COM port.
Forget MSD. I am talking about device manager and the PORTS category under
it. A serial port is not the same thing as a COM port. As I said a serial
port is a connector for an device such as an external modem. SOME internal
non plug and play modems in Win95 will have com2 under ports as well as
the modem under modems. For PnP modems, there will be no com2 under ports
if the modem is using com2. For external modems, the modem will be on com2
only because it is connected to a 25-pin/9-pin serial port on the back of
you computer, which causes the COM port address to be shown under PORTS.

And all internal modems that I know of have UARTs on it. My 14.4 modem has
a 16550a UART on it and my serial ports in my computer are only 8250. I
wouldnt be able to use an external modem on my serial ports since the UART
would be to slow for it.  External modems don't have UARTs built into them
because they rely on the UART of the serial port they are connecting to.
