u-blox
This example establishes a transparent link between the mbed serial port and the modem (LISA or SARA) on the C027. You can use it to use the standard u-blox tools such as m-center or any terminal program. These tools can then connect to the serial port and talk directly to the modem. Baudrate should be set to 115200 baud and is fixed. m-center can be downloaded from u-blox website following this link: http://www.u-blox.com/en/evaluation-tools-a-software/u-center/m-center.html
Dependencies: mbed
Install mbed Windows Drivers
Make sure you installed the drivers on your windows PC to get the virtual serial port. A installation guideline and the drivers can be found in the following wiki page. /handbook/Windows-serial-configuration
