I have a problem with my Stuart board. I saw in the docs that i should
first connect to the gumstix through the serial port and enable the usbnet
or the ethernet. But i can't connect at the serial port. I've started a
minicom on the host, but nothing happened. The cable is good. I've made
some measurements on the board and i saw that there is no signals on the
TxD pin (on both ports, and on the IC (MA3232) too).
What is the problem? Can somebody help me? What should i do?
