[WT-support] UDP socket #10013 Error

[ARC M.Pupin Belgrade]

Hi Dieter,

We had some problem at YU1EXY. Finally I have noticed that this is 
related with installation of  UMTS/HSPDA modems on specific computer. It 
seems that this installation  took over a range of ports.
I have tried few different ports but without success. As it happened in 
the contest I have not time for close look.
Deinstallation of Huawei modem software solved the problem.

Regards,
Zoran, YU1EW
