You need to debug who is using that port and then free the port. Probably, some application is using up your port at system startup only. I faced similar problem
The solution that worked for me was - I went to Device Manager from Control Panel, disabled that particular port and restarted the system. On system startup, I received an error of the application that was using this port. This way I was able to find out that app, I removed that application and hence the port was freed for my application 2009/11/25 Zebel <[email protected]> > Olha, para teres a certeza k o modem k pretendes usar funciona, de > principio ele tem d estar na lista de modems compativeis.
