No Serial connection with Tera Term


I just downloaded Tera Term to my computer and I am trying to set my "new connection" to serial for the mbed serial port. However, the serial option is grayed out. I tried updating the firmware on the mbed but it hasn't helped... I also tried updating the driver in the device manager. Any suggestions?

Have you re-installed the mbeds serial drivers? (See Ney Palma's links).
