As I commented previously, I finished the work required on the IECHost firmware to execute DOS commands.
This means I can now roll out options such as Delete file, Validate and Format disk, all of which are useful to get out of trouble should things go wrong.
As the counterpart is available in the IECHost firmware I will also allow users to issue custom commands through the command channel, a bit like it was done back in the day with something along these lines:
An extended example could be renaming a file:
OPEN 15,8,15 PRINT#15,"R:NEW NAME=OLD NAME" CLOSE 15
The fun is just about to begin! Stay tuned!
