3 ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
4 ;;
5 ;; FILENAME: CPS Printer Device Driver Main Code
6 ;; MODULE NAME:
7 ;; TYPE: Assemble file (resident code)
8 ;; LINK PROCEDURE: Link CPSPMnn+CPSFONT+CPSPInn into .EXE format. CPSPM01
9 ;; must be first. CPSPInn must be last. Everything
10 ;; before CPSPInn will be resident.
11 ;; INCLUDE FILES:
12 ;; CPSPEQU.INC
13 ;;
14 ;;
15 ;; This routine is structured as a DOS Device Driver.
16 ;; IE it is installed via the CONFIG.SYS command:
17 ;;
18 ;; The following device commands are supported:
19 ;;
20 ;; 0 - INIT
21 ;; --------
22 ;;
23 ;; 8 - OUTPUT
24 ;; 9 - OUTPUT
25 ;; --------
26 ;; Supported in between Designate-start and the Designate_end commands.
27 ;;
28 ;;
29 ;; 12 - IOCTL OUTPUT
30 ;; -----------------
31 ;; CPS Function request : Major function = 05 -- printer device
32 ;; Minor functions = 4CH -- designate start
33 ;; 4DH -- designate end
34 ;; 4AH -- invoke
35 ;; 6AH -- query-invoked
36 ;; 6BH -- query-list
