I've looked at Tibbo Em202, Digi Connect-ME & Wi-connect, DPacTec Airborne and gone for the Lantronix XPort & WiPort. I spent som time on the em202 first (climbing the learning curve on co redirectors, and then bypassing them and trying to connect directl using tcp/ip). Ultimately, I gave up on the em202 because I couldn' get it to go properly in a client/server mode, and comparison, th Digi & Lantronix modules worked properly. The Lantronix WiPort i cheaper than the Digi Wi-ME and the tech support in the UK is better
The detail on the em202 is that if the PC/virtual com port end is th
slave, it has to poke the link first to get it to start up :!: which was no use if the cable got disconnected and the micro wante to notify the Pc that it was connected again
