[En-Nut-Discussion] Dual rs232<->Ethernet

[asdus]

Yep, you're right. But rs232d primer have some troubles.
Yes, it's have buffers to resolve different speed problems, but
connection stucks, if ethernet client disconnect unclean, and,
sometimes, i'm have strange data freezes, when i receive sended data
only on next connection.
