MODE Err Msg: Function Not Supported on This Computer

ID: Q119595


The information in this article applies to:


SYMPTOMS

Typing MODE COMx:19200 results in the following error message:

Function not supported on this computer.


CAUSE

IBM PS/2-style computers support extended INT 14h services that allow the baud rate to be set up to 19200. MODE uses this extended function support to initialize COM ports on PS/2-style systems.

Most non-PS/2-class machines do not have a ROM BIOS that supports this extended functionality.


WORKAROUND

Rather than using MODE to set the baud rate, use an application that controls the COM port to set the baud rate.


MORE INFORMATION

This information is true for previous versions of MODE.COM as well the version in Windows 95.
