Appendix C - Differences Between
Software Revisions
This appendix describes differences between current revisions of the
software.
Revision B and Revision C
Interrupts
In Rev. C, the software is interrupt driven, improving its performance
and taking advantage of the interrupt capabilities of the GPIB-PC
interface board.
Startup Program
The Rev. C standard software package includes a startup program
(IBSTART.BAT) to get you started faster. Among other things, this
program creates or modifies your CONFIG.SYS file (IBCONF used to
do this).
Configuration Program
In Rev. C, the configuration program, IBCONF.EXE, is streamlined and
is easier to use. It no longer modifies CONFIG.SYS, since the start-up
program now does this. The Automatic Serial Poll and Lockout features
are now configurable at the board level.
Interface Bus Interactive Control Program (IBIC)
In Rev. C, IBIC.EXE includes a help feature. Also, you now call
IBFIND as you would in your application program. It must be called at
the beginning of IBIC.EXE to enable a device or board, and be called
subsequently to enable any previously unreferenced device or board.
