System requests will not work

When using Operations Console, SYSREQ corresponds to Shift+ESC and is defined as the default for PC5250 emulation.

Most keyboards have a Print Screen key, also labeled as SYSREQ and would be activated by using that key with the Ctrl key, however Windows^® reserves this key for the Print Screen function.

You must remap the keyboard by using the operating system, not PC5250, in order to change it.
