= SUMMARY =

Early versions of the IBM PS/2 Model 50Z were shipped with a serial port that uses a nonstandard interrupt. This has caused an incompatibility with the way Word, Windows, and Lotus 1-2-3 print to a serial port.

Microsoft has not tested our products with the Model 50Z and is not currently working on a patch for the problem. IBM has changed the port to use the standard interrupt in more recent versions of the Model 50Z.

Programs that use BIOS function calls to drive the serial port can communicate using the Model 50Z’s serial port. Also, programs that have been patched can use this serial port.
