Does anyone know the escape sequence for the F8 Function key for a VT220. Please don't reply with the VT52 or VT100 sequences, they are not the same. Thats the F8 key, if anyone happens to know it or knows where I might find it please respond. [ Alert DEC guru's ] Thanks in advance...

The following sequence will do it: ESC [ 1 9 ~ The spaces between characters are for clarity only. A complete listing may be found in Appendix D: VT320 Programming Summary, Installing and Using the VT320 Video Terminal. VT220 shares the same sequences. -- +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=+ | David Rackley |"The described functionality performed | | Applied Research Laboratories | flawlessly, unfortunately we had absolutely | | P.O.

If eight-bit control sequences are disabled, however, aren't the exact same codes produced by VT100's and VT220's? I don't remember ever writing special case code for the different terminals. --Rick Moll rick@wicat.com

I don't remember >ever writing special case code for the different terminals. The VT-220 generates standard VT-100 sequences for the keypad and the cursor controls, using either <CSI> or <SS3> prefixes as directed by the host-generated setup orders, and using either 7-bit or 8-bit sequences based on the terminal setup. As long as you're using 7-bit mode in the terminal the generated sequences are identical. The difference is in the keys which were introduced on the VT-200 but don't exist on a VT-100. This includes all of the keys along the top row and the six editing keys above the cursor pad. All of these new keys send the sequence: <ESC> [ <n> ~ (that's ESCAPE, left bracket, one or two decimal digits, tilde) The six editing keys send single digits 1 through 6: Find Insert Remove 1 2 3 Select Prev Next 4 5 6 (Note the nice pattern which matches the keytops on the keyboard.) The function keys along the top row (F6 through F20; the first five numbers are "assigned" to the terminal control buttons on the left) send two-digit numbers 17 through 34. The numbers skip a position where there is a gap between keytops (strange, but that's DEC's way of designing it), so F6-F10 use 17-21; F11-F14 use 23-26; HELP and DO are 28 and 29, and F17-F20 are 31-34. As noted by Dave Rackley, this makes the string emitted for F8 to be <ESC> [ 19 ~ Remember that the edit keys and all of the top row keys except F11-12-13 are dead and send nothing if the terminal is in VT-100 mode. In this case these three keys send ESC, BS, and LF respectively since there are no other keys on the keyboard for this purpose.
