The I/O commands accept a correction factor in percent in X. Try with 95 if your device is
a bit too slow or 105 if it is a bit too fast. Values between 80 and 120 are accepted all
other are ignored. On the emulator or with the crystal installed, x is ignored.

not contain said modification, the system will hang and can only be
brought back to live with a reset or a battery pull!
