| 1. | These are the control codes that the IVC responds to. They are normally sent to the IVC by a User program or the Host’s operating system. (See section 4 – PUTVID). |
| 2. | Programs that request information from the IVC will have to read the information back from the IVC. (See section 4 – GETVID). |
| 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). (Also see section 6.2 – Nested Escape sequences). |
