Setup: Zeos 386SX-16 2 serial ports (1 9-pin, 1 25-pin) on ZATIO2 card. Ports are switchable 1/3 and 2/4 (Com3=3e8h, IRQ4; com4=2e8h, IRQ3) 1 Everex Evercom 24 EV-940 internal modem, port selectable 1-4. Same port addressing as the serial card, plus a jumper to shift the modem to IRQ2 (IRQ9 on an AT). 1 Microsoft Serial Mouse, 9-pin 25-pin Serial cable running to Logical Connection (printer-sharing device). Problem: How do I get all of this to function in harmony? At the moment I have the mouse on COM1 (it doesn't work on COM3), the cable on COM2, and the modem on COM3. If I go into Windows and start up Terminal (yes, I know.), the mouse dies, and I have to reboot to bring it back. I have put the COM3Base=3e8h line in SYSTEM.INI, and tried switching between use of COMIrqSharing=true and COM3Irq=9, depending on the jumper setting, but I always get the same result. If I switch port 2 to COM4, DOS decides that it is actually COM3, and this SEEMS to cause some confusion; I'm not sure. Its effect is that when I try to print, both the printer and the mouse die. I didn't try this setup with the COMIrqSharing=true line, which may make the difference, but I doubt it. Any suggestions? -- Jason Merrill jmerrill@jarthur.claremont.edu
