Problem: Edgeport/2 USB to Serial installed on Windows7 Professional system.
Serial Port - 1 = (Com4) , Serial Port - 2 = (Com5).
Driver Provider: Digi International
Driver Date: 5/5/2010
Driver = 18.104.22.168
Properties reports - device is working properly.
Port Settings = 4800, 8, None, 1, Flow Control = None
Attached to Edgeport is XStream-PKG wireless modem with baud set to same as above.
Using HyperTerminal for communications.
After rebooting PC HyperTerminal reports following message:
Unable to open COM4. Please check your port settings.
I’ve check everything which seems to be ok. I have to disable device, reboot, then enable device. then all is works again.
I have also gone through unistalling and reinstalling which also fixes the problem.
Does anyone know if there is a driver problem with Window7? any other ideas would be helpful.
