Ok! An INTERNAL modem — if this was mentioned earlier and I missed it, I apologize. Your internal modem basically is it's OWN serial port — so you don't need to worry about any other serial ports in your system w/ regard to their UART — you DO have to mack sure that the modem's COM and IRQ settings don't conflict w/ anything else — including your other serial port(s). For example: Say your machine's I/O (whether on the motherboard or on adapter card) has COM1 and COM2. Your internal modem is set to COM3. Now, COM1 and COM3 share the same interrupt request line (IRQ), as do COM2 & COM4. So, that means that if you want to use your mouse (assuming that it's a serial mouse and not a bus or in-port type) while you're using your modem (say in Windows) then your mouse must be on COM2 — cause if it's on COM1 then it will conflict w/ the modem. My setup was (I now have an in-port mouse that plugs directly into the motherboard) my digitizer on COM1, my mouse on COM2 and modem on COM3 — since I never use my digitizer for aught but AutoCAD, I didn't get a conflict. Now, it may be that there is a jumper or DIP switch or modem-code setting to enable the 16550 compatiblity on the modem. Make sure that you don't have a device conflict as I described and let use know what you find out from the modem-makers. Dave
