1. In an interrupt-driven keyboard system, use of a type-ahead
console buffer can conflict with the cp/m's CONSOLE STATUS function #1.
Typing ahead activates the status condition, and a number of programs use a
positive status to abort. But if the status is changed to indicate to cpm
that no key has been typed it is then unavailable for programs that require
status before calling CONIN to get the typed character.
2. Discussions here have occasionally alluded to improving cpm's
error recovery capabilities. It would be desirable to be able to reset the
disk system within a running program, for example, if you've changed disks
and forgotten to warm boot before trying to write.
Any suggestions?
