Socat to UDP Server Truncating Last Character

Question

So I am working on a Serial to UDP gateway to link a point of sale printer to a NVR that can overlay the transactions on the Camera video (When the POS unit prints on the serial printer, this unit taps into the serial data to the printer, then on the NVR screen you will see the text of what the serial printer.

Here is my code so far :

/usr/bin/socat -d -d -d -u file:/dev/ttyUSB0,b19200,nonblock exec:/usr/bin/strings |/usr/bin/socat -d -d -d -u - udp:10.0.1.3:37777,reuseaddr,sourceport=51470,reuseaddr

The first Socat instance reads the data going to the printer. Passes it to strings to strip the non ascii data, then the 2nd socat instance passes it onto the NVR.

This is working fine, however on the NVR, for some reason it is missing the last letter in each line. It might be reading the newline, and somehow ignoring the last character. What I need to do is figure out why it is doing this, or possibly easier, just add a dummy character before the newline character.

This is what the first socat and Strings produces

A hexdump of what the first socat and strings produces is (the 0A i believe is the newline code)
