I want to send a complete *.ini file to the firmware [ST72C334]

I don't want made special software on the PC, so i must take standard protocols to send the *.ini file to the firmware.

I think the X-modem will be the easiest, [hyper terminal], but it sends packets of 128 bytes?

It's a lot, but the ST72C334 have 512 bytes RAM, so it can!

Has anybody build X-modem software for the ST7? [Assembler]

Is there another standard protocol which will be used by hyper terminal, that i can use with smaller packets?

hyperterminal can also be used for byte by byte transfer, Use Text file transfers. Or you can also implement handshaking.

The hardware is already finished and doesn't support handshaking.

Text file transfer used byte by byte transfer, but the receiver can't hold the transfer is it?

The receicved bytes must be wrtitten in the EEPROM.

Anybody other solutions?

Thanks for you're reply alok!
