General notes and comments, no real documentation is available.
If you need a manual, you probably do not need BOB. These notes
and the information displayed when BOB loads should be sufficient
information for most developers to use BOB.
1 - BOB is an acronym for Break Out Box.
2 - BOB requires X00 version 2.00 or above.
3 - BOB works best with a VGA controller card. The VGA (and
BIOS) must be IBM compatible. BOB uses some rarely used VGA
modes. I suspect many users will find their VGA is not
compatible enough to run BOB. I have successfully tested BOB
with IBM, Orchid, Paradise and Ahead VGA controllers. BOB will
also work on some IBM compatible EGA cards. However, most EGA
clones are not compatible enough for BOB to work correctly. I
tried BOB on about 10 EGA clones and none of them worked. Vince
Perriello's EGA, based on the Tseng chip set, is the only EGA
clone on which BOB has correctly executed.
4 - Future versions of BOB may require use of the HLLAPI routines
supplied with X00.
5 - Future releases of the HLLAPI routines that are distributed
with X00, will include function calls to selectively enable and
disable line monitoring and possibly trapping the data to disk.
6 - A program like ASC (from PC Magazine) is handy for quickly
determining the hexadecimal value of the displayed characters.
ASC is available from the Renex BBS at 703-690-7950. It is
located in file are 17.
7 - If a file name is specified for the trace data (eg BOB TRACE)
then two file handles are used. In some cases, users may have to
increase their FILES statement in CONFIG.SYS. The trace file is
opened at load time and is not closed until BOB is un-installed
or ALT-SHIFT F8 is hit. Once ALT-SHIFT F8 is hit, BOB must be
un-installed and re-executed to start trapping to disk again. A
clear screen (ALT-SHIFT-F1) causes a disk write and directory
update.
A program called ANALYZER, written by Bob Hartman, is included in
the BOB distribution file. This program will convert the BOB
disk files into a readable ASCII format. My thanks to Bob
Hartman for putting this program together. Execute ANALYZER and
it will display its command line options.
