Looking for serial communications techniques?

Hi

I looking for tried and tested serial communication techniques ( ZMODEM, XMODEM e.t.c.). I have worked with the Z-Modem but it is too slow. Do you know of any other techniques wich are far much better than the Z-Modem?

Thanks

    what compiler? did you change the baud rate to fastest possible? did you using interrupt processing to improve transmission ?

    The baudrate is not really the issue here. I used the Z-Modem technique to read in data that was almost 2MB but it takes too long to read the entire data. What I am looking for is a good method that I can use to upload large files.

    The compiler is also not the issue as well. What I am looking for is a fast method I can use to upload large files. For my final application I will send a file from one PC to the other. But I am not looking for software yet. I just want a good method that can be fast enough for me to send a file from one PC to the other using serial communications.

    Thanks

    Then don't use serial as there are no serial techniches that may be fast enough for your purposes -- sockets is probably the fastest and most common method. you might also check out ftp programs like this one:

    If the two pcs are sitting next (or close) to each other you can create a LAN, make the directories on each pc shareable, create network drives on each pc then use normal copy from one pc to another.

    >>The compiler is also not the issue as well
    It might be when you start coding.
