Sending Serial Data over UDP using Netcat in Terminal

I would like to be able to send serial data over UDP to another application. Eventually I wish to make this process into a shell script or something of the like because I will be running it on a linux based device.

In terminal I have tried this:

nc -u 10.0.1.3 7000 < /dev/tty.usbmodemfa121

IP: 10.0.1.3

Port: 7000

Serial: /dev/tty.usbmodemfa121

The udp port is openned but no data is being transfered or read.

If I leave it like this:

nc -u 10.0.1.3 700

I am able to send manually typed keyboard keys to my recieving application.

Does anyone have any ideas on what the problem is, or an easier cross-platform way to send Serial Data over UDP?

If you haven't already, I would try breaking down the problem. First confirm you're getting serial data then confirm that netcat can send some data. Like this:

xxd < /dev/tty.usbmodemfa121 | less

nc -u 10.0.1.3 7000 <<< 'hello over there'
