[Slashcode-development] Serial port receive - On Digi ME

[Jayaprakash S - T. Chennai. <jpr...@hc...>]

Hello All,

   I am using digi me with uCLinux.  I am trying to loopback the serial =
port
through a small program.  I am able to send the characters without any
problem, but the receive fails.  It either returns 'a' or 'EAGAIN' (I am
using non-blocking serial port).  I am not clear on how many ports the =
digi
can control at a time.  I am using both the ports.  One for console and =
the
other for my loopback test (The tx and rx are connected via a mating
connector).  Any pointers for me would be of great help.

Here is my serial port setup:

	// Get the current options for the port...
	tcgetattr(fd, &options);
	// Set the baud rates to 19200...
	cfsetispeed(&options, B19200);
	cfsetospeed(&options, B19200);
	// Enable the receiver and set local mode...
	options.c_cflag |=3D (CLOCAL | CREAD);

	options.c_cflag &=3D ~PARENB;
	options.c_cflag &=3D ~CSTOPB;
	options.c_cflag &=3D ~CSIZE;
	options.c_cflag |=3D CS8;

	// Set the new options for the port...
	tcsetattr(fd, TCSANOW, &options);




Thanks in Advance,
JP.
