Basemon is quite tolerant, it even responds without external
RAM. If you don't send spaces, it will automatically produce
some output at 38400 baud after some seconds.

I'd suggest to check the USART0 output from the CPU up to the
RS232 level converter. If you don't have access to an
oscilloscope, send the board back to egnite's Ethernut Clinic.
