TEST NAME : txrx

DESCRIPTION: This program set the terminal parameter with the requested baud rate
             using standard C library functions, and then transfer and recieve the 
             data for the duration of $RUNTIME seconds.

COMMAND LINE:
	     rx -d <devicename> [ -b <baud_rate>]
	     tx -d <devicename> [ -b <baud_rate>]

REQUIRED RUN TIME: ~8 hours

INFORMATION:
	     The tx and rx set the parameter with the requested baud rate using 
	     standard C library funtions tcsetattr, cfsetospeed, cfsetispeed and
	     tcgetattr. Once the terminal is set successful, tx transmit the data
	     at requested baud rate until $RUNTIME expires and rx recieve the data.

EXAMPLE    :
	     At reciever machine,

		rx -d <devicename> [ -b <baud_rate>]
         	The device name should follow the full path. The baud rate must be the 
		one supported in termios_p structure. Refer termio(7I) man page for
		supported baud rate.

	     At transmitter machine,

		tx -d <devicename> [ -b <baud_rate>]
		The device name should follow the full path. The baud rate must be the 
                one supported in termios_p structure. Refer termio(7I) man page for
                supported baud rate.

	    NOTE: The reciever and transmitter device can be on same machine or at different
		machine, but must be connected.
