Can someone tell the reason why the following code
fails, returning error
Filed to reopen
open(): Resource temporarily unavailable
....
while ( ( fd = open( "/dev/ttyS0", O_RDWR ) ) < 0
)
{
if ( errno != EINTR )
{
printf( "Filed to open\n" );
perror( "open()" );
exit( 1 );
}
}
.....
close( fd );
When I connect two PCs with serial line (rs232,
between /dev/ttyS0 and COM2(Win2k)), and run a java
application that opens a serial port connection at the
other end and just tries to read data from line.
Im using the following gcc version
gcc version 2.96 20000731 (Red Hat Linux 7.0)
