Read, Program and Debug the SXKEY using a QBASIC-program (QBL99V3.BAS)

If you only want to use the SXBLITZ-protocol on a SXKEY (rev-E or -F, thus with encryption) to READ and PROGRAM a SX28-chip, the recipe is very simple:

Create a program with SXKEY28L.exe and fill a SX28 with "Program" (your prototype)
Start the QBASIC-program (set the COMport on 1 or 2 in the second line!!) and give as command: <R> (READ)
In the DOS-directory you will find now the files:
- READ_KEY.TXT (with the content of the SX28 in readable form) You can rename that file and use this name for programming SX28 -chips in the field.
- DISDEBM.TXT (disassembled content of SX28 ). (Also the still "unknown" DEBUG-codes)
Program a new SX28 -chip with the command: <P> (Program)
You can write your own VERIFY-command in QBASIC if you like.

If you like to use the DEBUG-facility:

Fill the SX28 -chip with the DEBUG-command in SXKEY28L.exe and QUIT
In the QBASIC-program start with <R> (READ) and then <D> (DEBUG)

* The ESC-key give you the possible commands.

Nb: look in the file DISDEBM.TXT to see what particular debug-code the program: SXKEY28L.exe has created.
