[En-Nut-Discussion] 4-6 serial ports on the ethernut?

[Harald Kipp]

Hi Ovidiu,

The number of serial ports is limited by available RAM only
and 4-6 ports are no problem.

But I'm not sure, if I got you right. You are talking about
UARTs, right? The ATmega128 got two of them only. What
hardware do you intend to use for the remaining 2-4 UARTs?
