hello!

can anyone throw some light on how to tranfer files through serial port from front end of the application?
i used to tranfer files to the simputer from my native system through serial port using minicom...
these r the steps i do:
$minicom -o
simputer#cd /root/sqlite
simputer#ctrl + a+ z
select the file.....

now i need to create a front end(screen with send files button),catch the signal when button clicked and in callback funtion i need to code on transfering files to the simputer...i tried system call,fork and pthreads(where again i use system call in thread function), but i couldnt get complete control over minicom to execute cd/root/sqlite

regards,
sudha
