RS232 Terminal configuration
You will need a RS232 terminal emulator to communicate with U-Boot/Linux console. You can choose between:
We suggest you to use Kermit as Terminal emulator for RS232 connection. Minicom was sadly reported to have problems when communicating with U-Boot (ZModem data transfer). If you just need a simple serial console and not to transfer data through RS232, then GTKTerm is the perfect choice ! (gtkterm package in Ubuntu)
