[En-Nut-Discussion] opened TCP connection

[Alexander Baranov]

Hi.
I have to establish TCP connection and stay connected for a long time (e.g.
several hours).  I create a socket 'dirsock' , start accepting the
connection with port 23 (telnet)  - NutTcpAccept(dirsock, 23). When
connected, I go to an infinite looped command monitor. It works fine but if
I stop active data exchange (issuing monitor commands through telnet) it
hangs after 10-15 seconds of idle state  and reboots through watchdog timer.
Is it natural behavior of connected sockets without active data transfer or
I miss something as usual?
Thanks,
