Sending Data from GPS to two Virtual Ports in Ubuntu 12.04

[Sail323]

I'm trying to direct data from my GPS at "/dev/ttyUSB0" to two virtual serial ports created with "socat" to be used by OpenCPN and PolarCOM.

I've set up the virtual serial ports;

max@widget:~$ socat -d -d pty,raw,echo=0 pty,raw,echo=0
2012/07/16 11:32:22 socat[4150] N PTY is /dev/pts/2
2012/07/16 11:32:22 socat[4150] N PTY is /dev/pts/3
2012/07/16 11:32:22 socat[4150] N starting data transfer loop with FDs [3,3] and [5,5]

How do I send data from my GPS at "/dev/ttyUSB0" to my two virtual ports at "/dev/pts/2" and "/dev/pts/3"

It appears to me that I have configured the virtual ports to send data between each other.

I was able to accomplish this using Muplex, a soft NMEA multiplexer by user "marinux". Using the default configuration, OpenCPN connected to a virtual serial port at "/tty/PS0" and PolarCOM connected to 127.0.0.1:22000 (I couldn't get PolarCOM to connect to a virtual serial port for some reason).

Many thanks to marinux!
