hi

ive used the drivers here for comvdd and it worked
i used trsansmit from a master via the lan driver to another machine also running the same driver
and was able to control a proteus session over lan

infact several machine all listening on the same port

look down the page to the bottom for network serial driver

Hey drbizzarow

If you are using a PIC micro or similar, I would recommend using the ethernet controller from Microchip (ENC28J60 - SMD or PDIP - http://ww1.microchip.com/downloads/en/DeviceDoc/39662b.pdf)
It uses a SPI interface at the PIC-side, and very few other components.

- or maybe a PIC with integrated ethernet controller like the PIC18F87J60 (SMD only Sad

http://ww1.microchip.com/downloads/en/DeviceDoc/39762c.pdf )

An alternative could be a Realtek ethernet controller (RTL8019AS) - also lot of online information.

Which language do you prefer?

Microchip got a free TCP/IP stack writen in C18 (supports HiTech C also as far as I remember) - very usefull as it would be a nightmare to do it yourself. The stack shows how to make a lot of things, like http, ftp, tftp and snmp - and controlling the internal hardware in the PIC by these interfaces.

As far as I know there isn't any microchip driver for a "virtual ethernet comport" for windows XP, but maybe your application could be just as useful with a http interface?

You could use the stack to send simple packages to a PC, but how you easy can capture them i don't know - maybe some MATLAB or C++ could keep it simple.

Good luck (this i properly not a beginners project - I tried it and haven't succeeded yet - maybe a demoboard isn't such a bad idea - approx. 165 USD from Microchip)
