I am writing a database program that will be updated in real time, and MUST BE
RIGHT at all times. For disaster recovery (in case of a PC crash), I wrote code
that will allow two PCs to run the code in parallel. They are configured as
Master and Slave, and keyboard input on the master is sent via the RS232 port
to the slave, where it is put into the keyboard buffer, so the slave thinks
that somebody is typing on its keyboard.
I have made the source of this available to anybody who wants to use it, look
at it to learn about interrupts, or to hack it about to do what they want.
I would like to thank Alaric Williams for the tutorial on "The Black Art" of
writing interrupts on his home page, without which, this project would have
been a lot more difficult. Thanks also to Salvador Tropea for giving web space,
and for his friendly encouragement.
I do not have a home page of my own, but Salvador Tropea, the author of the SET
editor that we all use under RHIDE, has kindly hosted the routines on his Web
site, from where you can download them. There are three files zipped together
into PCMIRROR.ZIP: KB.C, KB.H, and a README which describes how to use the
code. To get the code, go to
...then follow the links to DJGPP, then again to DJGPP, then at the bottom of
the page, Mike Collins, "here" .
Don't just hit "reply" - my E-mail address is bogus

Actually, even this doesn't stop all of them ...
