How can send AT commands by hand (say, with HyperTerminal) over the virtual USB Port?
The reason is, that the DB9 conncetor is reserved for another external device.
You need first to install the USB drivers for BGS5.
Additionally con can setup the serial port to obtain the AT-command port and modem port over USB
In Hyper terminal select the port and 8-N-1-None, using USB you have not to take care about the baudrate
Somewhere over the rainbow!!! Looking for the Oz Land!!!
Thanks, its working now.
Hi,I have been able to connect a hyper terminal to the USB port however I get back garbled text and "SIO:" To me it seems like a charset problem but I have at+cscs="UCS2". Connecting the hyper terminal via ASC0 (db9) I have no problems with at+cscs=UCS2 or GSM.
Any ideas are appriciated.
Please check AT^SCFG? command reply for "Serial/Interface/Allocation" parameter setting.
If the reply is ^SCFG: "Serial/Interface/Allocation","1","1" the USB1 interface which you can see in the Windows Device Manager is reserved for internal tracing.
Please type at^scfg="Serial/Interface/Allocation","2" and restart the module. After that USB1 interface will reply to AT commands.
That did it. Thanks!
