Byte-Back Printer Interface

Al Rapp of Blowing Rock, NC writes: I am using the RS-232 board in my Byte-Back modem and Byte-Back’s printer driver program to drive my Star DP8480 serial printer. I can copy the whole screen by using USR 8347 at line 3020 of PRO/FILE but I can’t select lines to be printed.

You must alter PRO/FILE’s printer codes:

POKE 16674,6 
POKE 16675,0 
POKE 16676,205 
POKE 16677,93 
POKE 16678,32 
POKE 16679,42 
POKE 16680,14 
POKE 16681,64 
POKE 16682,195 
POKE 16683,126 
POKE 16684,32

Also, change BASIC lines so they read:

3010 POKE 16675,C2 
3020 RAND USR 16674 
3036 GOSUB 3500

Finally, add these BASIC lines:

3500 CLS
3510 PRINT
3520 RAND USR 8351 
3521 RETURN

This routine works when Byte-Back’s printer driver is located at address 8347 for LCOPY.
