Etherlite TS 32 v3 Realport v3.1.243

Attached is a wireshark capture on the client machine running Realport version 3.1.243. The TS 32 device is running firmware version 1.7.

We are experiencing a buffering issue where it requires a second command from our remote terminal (1200bps) to flush the buffer in the Etherlite device. We can see this by attaching two protocol analyzers on either side of the Etherlite device.

Is this is a known v3.1.243 problem? If so has it been resolved in v4?
