zalt's Issues

[SysCtrlr] Add help for terminal commands

More guiding help for the commands.

Add a help command that lists all commands
Provide help/details on parameters
Repeat (echo back) partial commands to let user finish it

[SysCtrlr] Add VT100 Terminal support

As prototyped in separate project (PSoC Creator/Terminal).

[IOProcessor] SysCtrlr acitvates WAIT too slow for Z80 at 20MHz to detect

When the Z80 running at 20MHz makes an IO request towards the System Controller, the SysCtrlr is too slow with activating the WAIT signal. The Z80 IO instruction is already done when the Z80 detects the WAIT request.
Tested with 'hello world' test program that outputs characters to the terminal (via the SysCtrlr).

@18.666 MHz it works. So its nearly there.
