I've been trying to install a generic MouseSystems Compatible mouse on the serial port of my ThinkPad 380d - I'm getting tired of all that cut-and-paste when using the built in "mouse".
The machine is running Windows 95 and RedHat 4.2. Under 95 I see that COM1 is the IRDA port and COM2 is the 9pin out the back. The mouse works just fine on COM2 (under '95).
Linux recognizes COM1(ttyS0) but not COM2(ttyS1). When I try to force the configuration of both via rc.serial (same address, IRQ, etc) gpm gets EIO errors on ttyS1. I've tried gpm on both ttyS0 and ttyS1 (with and without rc.serial) with the same non-result.
Any suggestions? This is getting frustrating.
