Serial terminal app help, sending hex to I/O board, OK with Realterm-Windows, Not Moserial Linux

edward3

I'm trying to do a basic communication test of an I/O board (on Linux Mint) that uses a 9-bit hex string. You send a read hex string to the board, it responds with a reply hex string.
Pretty simple, it works fine using Realterm on Windows, but I'm struggling to get a response using Moserial on Linux.

Moserial doesn't have the granular settings found in Realterm, the basic settings look correct, but I'm getting no reply from the device using Moserial.

The green test hex is the sent hex string, the yellow is the reply.

Any advice or suggestions, or a better serial app would be appreciated.
