[comp.terminals] TEK 4014 Info Request -- Summary

mch@ukc.ac.uk (Martin Howe) (05/12/89)

Someone asked for a summary of what I received, so here it is:

Apearently Kermit manual for MS-Kermit, has a fairly detailed description of
Tek terminal codes; what's more, one can try looking through the source code
to MS-Kermit itself, since the code is available free (it is written in 8086
assembly language). Kermit is available from Columbia University.

As for the TEK 4014 Incremental Plotting Mode, this is a plot preview mode
to enable you to look at plots that would normally go to a pen plotter.
I it may be possible to connect a pen plotter to the back of a 4014 and it
will draw the plot on the screen and send it to the plotter. Only commands
received during 'incremental plot mode' actually go to the plotter.

To use this mode one moves the beam to the desired position using the normal
GS vector mode, then one places the terminal into incremental plotting mode
(using RS) and then send all the movement commands. Then go back to ALPHA mode.
The available commands pen up, pen down & motion.

	Character Dec Binary	Action
	========= === ========= ===================
	space	  32  001 00000	pen up (beam off)
	P	  80  010 10000	pen down (beam on)
	D	  68  010 00100	North
	E	  69  010 00101	North East
	A	  65  010 00001	East
	I	  73  010 01001	South East
	H	  72  010 01000	South
	J 	  74  010 01010	South West
	B	  66  010 00010	West
	F	  70  010 00110	North West

The beam can move, vertically, horizontally and in both diagonals. The above
table steps from North, clockwise until North East.

US or CR or ESC FF (or Keyboard PAGE or Keyboard RESET) will take you back to
alpha mode. Note that if your 4014 understands Incremental Plot mode then it
has the ENHANCED GRAPHICS MODULE. This module is NOT standard on all the 4014.

This information is taken out of:

	Tektronix 4014 and 4014-1 Computer Display Terminal
	Users Instruction Manual
