Hello Sean,

My name is ---Deleted Contact Data-- and I am the Technical Support engineer responsible for Europe, Middle East and Africa.

This question is more suited to send to Lantronix Technical support using the following link:http://ltxfaq.custhelp.com/app/utils...m/redirect/ask

The current firmware of the UDS2100 allows only a single socket connection to a serial port. The hardware allows more socket connection, but that will require modifying the firmware. We have a free Software Development kit called CPK. This will require knowledge of embedded programming as you will need to build up the firmware from scratch.

An alternative is to use UPD instead of TCP

The EDS2100 could be a good alternative if you can setup the connection from the EDS2100 as this has a feature called simultaneous tunnel.
Please see the following link:http://ltxfaq.custhelp.com/app/answers/detail/a_id/1648. (Please rename the file with an extension .pdf!)

Hopefully this helps,

Greetings,
