Can you use a serial mouse with a PS/2? A lady in one of our offices has a PS/2 Model 50Z ... she has ordered a BSR serial mouse. I've only seen PS/2s with IBM brand mice attached. We have always referred to these mice a "PS/2 mice". Obviously, I have a lot to learn about this ... any assistance will be greatly appreciated. Ron Yarnick RVY2@PSUVM

The reason why PS/2's have a mouse port is so that you can have a mouse without taking up a serial port. The serial port on the PS/2 is configured as COM1, although you can change this with the reference disk. ----------------------------------------------------------- The Time Traveler Sadder still to watch it die a.k.a.

I heard someone say that the official maximum of a PS/2 serial port is 57600 Baud, but I took mine to 115K baud. Like I said, it's identical to every other PC serial port. I have no idea what the mouse port is like. I assume it's similar to a serial port. ----------------------------------------------------------- The Time Traveler Sadder still to watch it die a.k.a.

As I stated in another newsgroup, the mouse port is identical to another keyboard port. If you attached another keyboard to the port and knew enough to replace the appropriate vectors, you would have a dual keyboard machine. (IBM has hospital offerrings where the second port uses a light pen that behaves like a keyboard.) On the matter of "how fast the serial port," that will depend on your machine and your interrupt handler. The faster the machine, the quicker it can process each incoming byte. Thus, the same machine's serial port is likely to work at a faster speed if you are able to replace its innards with the Power Platform.

Unless I am grossly mistaken, the upper limit is 115,200 bps. But heck, even my old PC-1 can do that (technically, anyway, altho the CPU might not have the horsepower to handle the data). Anyway, I don't offhand recall the UART used in the PS/2s (may be the good old 8253) but that would be the determining factor as far as top speed. Dave the DM bank@lea.csc.ncsu.edu
