SEND TEXT file with serial port

If you want to send a file from your computer to your microcontroller, use for example the HyperTerminal....then select transfer-->send text file
This will send the file character by character.
You can send any file, I use this to send my *.hex file when using a bootloader.

In the configuration menu, inside ANSI options you can set the delay between characters and between new line.
(Usefull when you send a big file and the buffer in the microcontroller is small)

The OP didn't say which direction the "file" was to be sent!

I guess there must be at least a 50% chance that he wanted to send it from the PC to the microcontroller...

In that case, it'd be easier to just do:

COPY file COM1:

"You can send any file"

It would not be a good idea to send anything other than a text file this way...
