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. >Julian Cowley <julian@uhccux.uhcc.hawaii.edu> 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.
