Hi Tinu,
I am doing something similar, and I am using AsyncPro with Delphi5 but
AsyncPro will work with C++ if you are more comfortable with it. 
AsyncPro is great because you do not have to deal directly with the
serial port will work with USB to RS232 adaptors, as lots of useful
features including RS485 mode and is free.

Here is the link:

Hope it helps.

Best Regards
		Luis

Subject: [TECH]: Data transfer between a PIC and a PC (easy solution for
thePC side). How to?

I need to transfer data between a PIC based application and a PC. The PC
is
used as an MMI for the application, i.e. it configures the parameters
for
the PIC and shows the status of the application.

A few years ago, i did such things using borland c++. this allowd me to
program an mmi which generated command sequences for the PIC and
interpreted
it's status messages. as this was win98 based, it allowed to 'directly'
access hardware, i.e. accessing the serial interface of the PC (rs232)
was
relatively simple.

Now, i'm using winXP and my old applications do not work anymore, as
hardware access of winXP is completely different...so i have to do
something
new.

What's the easiest way to write a PC application, which gives acces the
PC's
interfaces?

I think to be a bit more future proof, using USB instead of the serial
interface (rs232) would be a good idea, but as a fall-back-solution, the
serial interface would be possible too.

how can i access these interfaces in a simple way with today's
technology?

thanx for your help!
