|3.||It may not be possible to issue commands to the IVC direct from the
keyboard attached to a system, as the operating system may modify the
charactera typed. (eg the standard CP/M line input routine would echo
“*[” to the IVC if the ESCAPE key were pressed, rather than the
ESCAPE code. – However note that this problem can be solved in Gemini
CP/M systems by selecting “EDIT mode”, where all characters are
echoed to the IVC exactly as typed).|
