Thanks for the info. It looks like the drivers are available from Quatech. I'll give them a look and let you know if I discover anything useful. Have fun!

>I am using AirBorne serial bridges from DPAC. And I am using their vcom utility. But because I did not know how to download the utility I gave you a link to another one. I am going to switch to it pretty soon. That utility is capable of constantly pinging the device and as soon as the device is disconnected for whatever reason the program creates a record into a log file. My program will monitor the log and reopen the port if needed. The utility even can reopen the port but it takes too long for it. About 20 sec. That is too long.
