Following a reboot I can telnet to port 2001 and establish a connection to the serial device. After disconnecting the telnet session and leaving it idle for about 15 minutes I cannot re-establish the connection.
I receive [TELNET] TCP error: receive failed.
I am able to connect to the DIGI One SP with a browser, log in and reboot it. Then I am able to telnet to port 2001 and establish a connection to the serial device again.
How can I prevent having to reboot each time?
