[En-Nut-Discussion] Serial transfer timing.

[Matthias Ringwald]

hi tamas

nut/os uses the cpu clock for serial port timing. here, either you 
explicitly set it via a #define (I guess its NUT_CPUFREQ or something 
like this)
or nut/os determines the cpu clock at runtime using the 32 khz 
oscillator. from this, it correctly calculated the serial timing. nice. 
?
