I have a 386 machine with a micro386 circuit board. It comes with many things on board, including EGA, two serial ports and two parallel ports. Things were working great -- I had a mouse on one serial port and a modem on the other. I moved the machine from one room to another and both serial ports died. Both the mouse and the modem stopped working. I tried the mouse on another computer and it worked fine. I even bought a serial board, disabled the on-board serial ports and tried those. No go at all. What really seems weird to me is that I put an LED tester on the serial port my mouse was on (between the port and the mouse connector) and I saw activity on pins two and three (receive and transmit) whenever I moved the mouse or pressed a mouse button. Any mouse program (including the mouse test program from Kraft, who makes the mouse) is just frozen -- the cursor does not move. I tried reloading the mouse driver from floppy; no change. Of course the modem went out at the same time, so I didn't really suspect the mouse, but seeing it work on the pc6300 (AT&T clone) made me feel sure it was the port. Does anybody have any idea what could be causing this? Anything else I could try? geoff sherwood
