serial: ttyS0

cardias · 09-01-2004, 09:56 AM

hi!
i've written a program to send and read raw data through serial port (/dev/ttyS0). it works fine, but during the read() i have to poll until a get the expected amount of bytes in the buffer. i would like to use the IRQ to wake up my read() process when the buffer is ready to be read.
i would appreciate any suggestions.

thanks,
cardias.

Can't use IRQ's in UNIX/Linux (unless you're doing kernel programming).
