UCSD Editor does not work

[z80micro-mc]

The editor does not accept CTRL/C as ETX hence there is no way to complete input of a line.

I suspect that the keyboard definitions / BIOS are incomplete. The lack of filetransfer facilities and the non-working editor render the system 'an interesting curiosity'

I have tried both TeraTerm and Putty as the terminal emulator both fail to be recognised by the editor.
