Yes, if you have a look at RoboRealm at http://www.roborealm.com/ you
can read in signals from the COM port using the serial module and
actually display that value using the built in webserver (or you can
save it to disk, send it somewhere else, etc.)
Let us know if you need any help with that.
There are Java libraries for serial communication. Add a MAX232 and
you're away. Course you have to use Java which might not suit.

I've been playing with "just basic" for reading data from a PIC micro
via the serial port. I've only really used a windows interface, defined
by the program but I have read on comp.lang.basic.misc about people
using Liberty Basic for writing a web interface.
I made a simple cgi application using freebasic for web based I/O
with the lynxmotion ssc-2 servo controller (below). You could
easily do the same using apache as your web server.
I did pretty much the same but with the WinIO driver from here:
which is pretty good at bypassing all the protected-mode stuff the later
versions of Windows imposes. It also handles parallel ports.
Many thanks for all the posts, Yes first of all I wanted to do a generic
"cross platform" app or webpage but i think for now I will choose a OS get
it up and running and then port it to the other OS'es.
many thanks again
I was at www.lvr.com the other day... VB Express (FREE) has a dedicated
serial class...there are examples and links to examples.
It should be easy to find examples for your micro to interface to a
Try forums for PIC:
Web search engine.
By the way, does it have to be serial? The Microchip ENC28J60 is pretty
easy to interface to Web intefface, as it only has 28 pins and I got
some free samples off microchip and you use a Web browser and Cat-5 cable...
Microchip has a new kid on the block the 18F67J60, integrated
Ethernet/PIC on the same silicon.
Also Fred Eady at www.edtp.com has some economic stuff. He writes in
Circuit Cellar mag and what he doesn't know about embedded ethernet
isn't worth knowing...
/* He has a new kit that has ethernet and serial onboard */
Microchip has a free stack and sample code - all you need to do is
modify some HTML etc.
Also the RealTek ethernet chip is featured often interfacing with PICs.
www.modtronix.com, an Aussie store sells some kits and they have free
examples that are excellent , the best I have seen using the RealTek chip.
If you can communicate with the microcontroller via the serial
port on a pc, then you probably can run a webserver like apache
to handle the web page part. I made a simple cgi application to
be able to communicate with a Lynxmotion ssc-32 servo controller
via apache and a web page. The below link has a quick write up on
