Chapter 3: Serial Port, Device and User Configuration

Encrypt Traffic / Authenticate
Enable trivial encryption and authentication of RFC2217 serial
communications using Portshare (for strong encryption use VPN).
Accumulation Period
Once a connection has been established for a particular serial port (such as a
RFC2217 redirection or Telnet connection to a remote computer), any incoming characters on
that port are forwarded over the network on a character by character basis. The accumulation
period specifies a period of time that incoming characters are collected before being sent as a
packet over the network
Escape Character
Change the character used for sending escape characters. The default is
~.
Replace Backspace
Substitute the default backspace value of CTRL+? (127) with CTRL+h (8).
Power Menu
The command to bring up the power menu is
~p
and enables the shell power command so a
user can control the power connection to a managed device from command line when they are
Telnet or SSH connected to the device. The managed device must be set up with both its Serial
port connection and Power connection configured.
Single Connection
This limits the port to a single connection so if multiple users have access privileges
for a particular port only one user at a time can access that port (i.e. port snooping is not
permitted).
