Hi Folks, We've recently developed a serial mouse driver for a Unisys PC running SCO Xenix. Since moving the driver from OS version 2.2(.3?) to 2.3, the message: serial: WARNING: interrupt vector collision has begun to appear. The mouse plugs into either COM1 or COM2, interrupting on vector levels 4 and 3, respectively. We remove the vector level associated with the mouse from the standard serial driver (sio), so the resulting configuration lines look as follows: sio 3 0577 104 sio 0 0 5 1 7 4 33 34 0 mse 1 0537 104 mse 0 0 27 1 5 3 0 0 0 I don't see a collision here. Is this OS confusion, or are we doing something weird? Both the mouse and the other serial port (connected to a terminal) work fine. Appreciate any suggestions!
