Hi Guys,
I am looking at a project purely for personal reasons, and am wanting
some advice before I get really stuck into it. I hope you can point me
in the right direction.
What I would like to know about is comms implementations with VBA. For
this 'hobby' project I would need to make an app that would allow the
use of a serial port / modem to communicate via both ZModem, VT100,
and also some proprietary comms protocols. I also need to be able to
use some of the serial comms based protocols over TCP/IP (its a type
of integration with some very old legacy hardware that has simply been
'interfaced' from serial (rs485 and rs232) to TCP/IP.
There is a book from Richard Greir(?) on the topic of serial comms and
I am lead to believe that it is the definitive work for such things. I
have played with this area before but I really need to get to detail
to do this correctly. Is this book a help?
Does anyone know of a VB / VBA implementation of ZMODEM that does not
require any external library files or dependancies? Same for VT100?
Your advice is always welcome.
Cheers
The Frog
