675.0. "Echo or log screen to a file" by GENRAL::WOOD (Celeste Wood) Mon Jan 25 1988 15:08

    I want to save the contents of my screen to a file so that I can
    mail it to someone.  Is there a way to echo your screen to a file
    like when you echo the contents to an attached printer with 
    the Esc[5i sequence?  
    No one seems to know if this can be done in VMS.  It seems reasonable
    to me.  How else are you going to debug a command sequence?
    I need to record both the commands I am entering and their responses.
    
    For example : Show Quota

    Thanks for your help, Celeste

	The "DCL" command in the EVE editor is very nice for recording (portions of) DCL sessions. (It's the only reason to ever use EVE, imho...) - John

675.4	s.th. in the TOOLSHED	UNTADG::SACHSE	life := (2b).or.(.not.(2b))	`Tue Jan 26 1988 04:15`	16
	For a REGIS terminal, you may use two tools in the toolshed: GRAFDUMP (unreliable) and (better) CAPTURE. Both of them use the (undocumented?) sequence <ESC>[?2i to redirect the output of the following 'graphic dump screen' sequence (don't remember exactly what it was) from the printer port to the communications port. Then, they just read strings from the terminal that ARE the dump of the screen (sixel mode). I've tried to do an <ESC>[?2i ('redirect "dump screen"-output to comm.-port') followed by an <ESC>[i ('dump screen') on a VT220, but that didn't work. Maybe somebody else reached to do this on a non-REGIS terminal ? BTW: There's just a few documentation to both of the tools, but you should be able to do it with that.
675.5	Continuing with SACHSE's CAPTURE note	VIDEO::OSMAN	type video::user$7:[osman]eric.vt240	`Tue Jan 26 1988 11:54`	16
	After I've used CAPTURE to copy my screen to a file as sixels, is there another tool I can then use on the sixel file to convert it back into characters ? Also, please note that the sixel dump and the SET HOST/LOG are totally different paradigms, and it's not clear which the original imposter was asking for. For one thing, SET HOST/LOG is useless if you didn't think to do it beforehand, and suddenly you have a screen you'd like to save in a file. For that matter, CAPTURE might be useless to, since to type the CAPTURE command means altering your screen. Perhaps you can type CAPTURE on another terminal but I doubt it. /Eric
675.6	All the same problems	UNTADG::SACHSE	life := (2b).or.(.not.(2b))	`Wed Jan 27 1988 02:57`	29

I've never seen a sixel-to-text conversion utility (if you think about it, it must be really hard to do), but there is no problem in printing this out on a LA50 upward, or including it into a document (either with RUNOFF or DOCUMENT). � Also, please note that the sixel dump and the SET HOST/LOG are � totally different paradigms, and it's not clear which the original � imposter was asking for. Maybe .0 (Celeste Wood) should specify more exactly what the tool should do. � For that matter, CAPTURE might be useless to, since to type the CAPTURE � command means altering your screen. Perhaps you can type CAPTURE on � another terminal but I doubt it. You need to have thought of dumping the screen beforehand, because you need to set some LAT Terminal characteristics to do it. But it would be possible to broadcast the escape-sequence from another terminal to the terminal-to-be-dumped, then (how?) read the dump file from this terminal into a file. Nice challenge, isn't it ? -Joachim
675.7	rathole-f-abort, Switch to new note	PASTIS::MONAHAN	I am not a free number, I am a telephone box	`Thu Jan 28 1988 03:55`	10
	re:.6, but a rathole from this note, Sixel to text should not be that difficult. There are document scanners that work with similar data, the only difference is that their data is much less predictable in font, scale and errors. Given a standard DEC screen of text, you know the font, you know there are no graphics, you know the scale, and you know there are no errors. I am not familiar with sixel, but I would expect a very hack algorithm (such as, if such a bit is set it must be an 'e') would work.
