  But when i try from the redboot by giving  " load -m xmodem "
 its showing. " CCCCCCCCCCCCCCCCCC "

  I think it is not necessary to give any file name. Is it the right way .
 the file hello1 is in  "/root " folder. sall i specify the path.

  thanks
     Pai

[...]

I never had much luck with minicom.  I always found the UI
excruciatingly painful, and there were times when it didn't
seem to configure the serial port properly.  Sending a plain
text file never worked right for me either.

I always used Kermit and the "sx" program, and never had any
problems.
