Trying to get serial Ping Example to work

[BoilermakerTobes]

I am struggling to get the PingAgent Serial example to work.

I compiled the example using

gcc main.c -lmicrocdr -lmicroxrcedds_client

I then ran it using the following command: ./a.out /dev/ttyUSB0 where I have my serial device ftdi on running at 57600 baud

On my agent side I ran both sudo MicroXRCEAgent serial --dev /dev/ttyUSB1

sudo MicroXRCEAgent serial --dev /dev/ttyUSB1 -b 57600 where I gave a baud rate

However I keep on getting "Sorry, no agent available at device '/dev/ttyUSB0'" I know that I have a connection because I can see lights blinking on the TX side of my client and RX side of my Agent during the ping. Am I doing something wrong with the setup of my client and agent? Is there another example I can look at for serial communication?
