I have made a mistake trying to get the GPS module to work on my EHS8 concept board, I have ASC0 set as stdout and I accidentally changed the GPS interface to USB0. So now i cannot figure out how to send AT commands as USB0 (left hand USB) is blocked due to the GPS module and the right hand USB is blocked due to stdout. 

How can I rectify this?

Hello,

Please see in Device Manager (in case of windows) under Ports that there should be more USB interfaces available for the module. Please use one of them.

Regards,

I found a port that worked. had to also change the baud rate. Not all USB ports can parse AT commands either.

Yes, not all USB ports have AT commands parsers - please see "Serial/Interface/Allocation" parameter of AT^SCFG command for more details.

You should not need to set baudrate for USB inetrfaces but only for RS232.
