 160 /	THIS IS THE CONSOLE OVERLAY FILE FOR KL8 TYPE CONSOLE SUPPORT WITH
 170 /	STANDARD BUFFERED LPT: AND I/O ERROR HANDLING CAPABILITIES.
 180 
 190 /	ASSEMBLY PARAMETERS.
 200 
 210 /	SETTING OVTYPE=1 GENERATES A STANDARD OVERLAY (DEVICE 03, 04 CONSOLE
 220 /	AND DEVICE 65, 66 LPT:).
 230 
 240 /	SETTING OVTYPE=2 GENERATES A NON-STANDARD OVERLAY (DEVICE 03, 04 CONSOLE
 250 /	AND DEVICE 40, 41 LPT:).
 260 
 270 /	SETTING OVTYPE=10 GENERATES A DECMATE OVERLAY (DEVICE 03, 04 CONSOLE
 280 /	AND DEVICE 32, 33 LPT:).
 290 
 300 /	SETTING OVTYPE=60 GENERATES A NON-STANDARD OVERLAY (DEVICE 40, 41 CONSOLE
 310 /	AND DEVICE 65, 66 LPT:).
 320 
 330 /	SETTING OVTYPE=61 GENERATES A NON-STANDARD OVERLAY (DEVICE 40, 41 CONSOLE
 340 /	AND DEVICE 03, 04 LPT:).
 350 
 360 /	ADDITIONAL TYPES CAN BE DEFINED FOR OTHER DEVICE CODES.
 370 
 380 /	SETTING LPBUFF=1 GENERATES AN OVERLAY WITH LPT: BUFFERING ENABLED.
 390 
 400 /	SETTING LPBUFF=0 GENERATES AN OVERLAY WITH LPT: BUFFERING DISABLED.
 410 
 420 /	SETTING LCASE=1 GENERATES AN OVERLAY WITH LOWER-CASE CHARACTERS PASSED.
 430 
 440 /	SETTING LCASE=0 GENERATES AN OVERLAY WITH LOWER-CASE FOLDED TO UPPER-CASE.
 450 
 460 /	SETTING VT8LPT=1 GENERATES INTERRUPT ENABLE FOR A DEVICE 66 LPT:
 470 /	SHARING INTERRUPT CONTROL WITH THE VT-8/E KEYBOARD (DEVICE 43).
 480 
 490 /	SETTING VT8LPT=0 GENERATES INTERRUPT ENABLE FOR DEVICE 66 ALONE.
 500 
 510 /	SETTING ONEWAY=1 ASSUMES A HARDWARE HANDSHAKING (CENTRONICS, ETC.) TYPE
 520 /	INTERFACE TO THE LPT: WHICH HAS NO INPUT HANDLING.
 530 
 540 /	SETTING ONEWAY=0 ASSUMES A SOFTWARE HANDSHAKING (<^S>/<^Q>) TYPE INTERFACE
 550 /	WITH SUITABLE INPUT HANDLING.
