I'm looking for something which will allow me to make sense of the various codes returned by VTnnn (nnn>=100) terminals when they are hit with a 'what are you' sequence. E.g. ESC[?1;<n>c seems to indicate a VT100, where <n> is between 0 and 7 and (I hypothesize) somehow indicates the presence of optional features. An emulator we've got which claims to look like a VT320 says ESC[?63;1;2;4;8;9;15c; another which claims to look like a VT200 says ESC[?62;1;2;6;8;9c. Again, I hypothesize that the first number indicates type, and the trailing list indicates features. Specific things I'm looking for are: 1) How much of the string do I need to look at to determine the basic terminal model, and what value(s) correspond to what model. (This would be enough info for my basic needs.) 2) (Less important) Does the rest of the list indeed indicate subfeatures, and if so, which values indicate what features? Do these values have the same, or similar, meanings across models? Does anyone have this information in a form that could be emailed to me? Or, is there some official 'summary' DEC document that I could order from DEC UK as an interested individual who doesn't have a customer account? (I don't REALLY want a complete set of DEC VT-terminal manuals.) For my purposes, info up to VT220 would be sufficient, as we don't have many higher numbers lying around. Out of general curiosity, though, info on higher models would also be interesting if you've got it. -- Paul Smee, Computing Service, University of Bristol, Bristol BS8 1UD, UK P.Smee@bristol.ac.uk - ..!uunet!ukc!bsmail!p.smee - Tel +44 272 303132

All the information you require is contained in a small manual entitled VT330/VT340 Programmer Reference Manual (Vol 1: Text Programming). It's DEC number is EK-VT3XX-TP-002. Your local sales office should be able to help you get this. In the mean time, here is what the message means: The return value from a "who are you" sequence is of the form CSI ? Psc ; Ps1 ; ... Psn c Where CSI is the Control Sequence Initiator ( ESC [ ), Psc is one of: (this is a subset of the full list, I believe) 1 VT100 6 VT102 12 VT125 7 VT131 62 VT200 series (220 or 240) 63 VT300 series (330, 340...) Ps1 - Psn indicate what options are available on the terminal, as follows: 1 132 columns 2 Printer port 3 ReGIS graphics 4 Sixel graphics 6 Selective erase 7 Soft character set (DRCS) 8 User-defined keys 9 National replacement character sets 13 Local editing mode 15 Technical character set 16 Locator device port 18 Windowing capability 19 Dual sessions This is an incomplete list of the possible values which can be returned, but it should get you going. Your local sales office should be able to get you more detailed information in the form of a programming manual. -chuck
