I have been playing with the gemini version of CPM. It does some interesting things
with the input mode. Because of this I found a bug.

The SVC Command ESC K returned 0 if no characters were available for input else returned the character. Reading the spec properly if no character is available it is supposed to wait for a character. What was happening was that this was returning 0 for no character and forcing the gemini bios to enter edit mode. This was causing problems.

While we are on the subject one of the other problems is the keyboard mapping is fixed and the cursor keys are not the same as the gemini choice. I am thinking of an easy way to do this as different systems use different key mappings.

Please download the latest version from http://81.105.120.101/download/xbeaver.tgz for this bug fix.

Thank you.
