Send a file thru RS232

It depends on what you want from this protocol. If you don't need error detection or stuff like that, you could just send the whole file byte-by-byte in one big chunk of raw binary data.

Just one big chunk of binary file...do I use the Z-modem protocol or is there a better one? Also, how would I set it up in my C-code for the 8051? Is it just the same as reading from RS232 thru hyperterminal?

Are you talking about uC to uC, PC to uC, modem or what ?

PC to uC...thru RS232

"raw binary data"

be careful that your PC is set up to allow raw binary data - ie, no software flow control, etc!

This is the very reason that Intel Hex format was developed (and other similar schemes like the Motorola S-Records, and UU-Encode)
