5:  Commands and Levels 
EDS-MD® Wired IoT Device Gateway Command Reference  75 
 
Clears the RSA/DSA certificate selection. 
Discontinues sending email alerts upon establishing 
an accept mode tunnel. 
Discontinues sending email alerts upon closing an 
accept mode tunnel. 
Removes the accept tunnel Initial Send string. 
Enters the next lower level. 
Uses SSH protocol for accept mode tunneling. 
Uses SSL protocol for accept mode tunneling. 
Uses TCP protocol for accept mode tunneling. 
Uses TCP protocol with AES encryption for accept 
mode tunneling. 
Uses Telnet protocol (with IAC) for accept mode 
tunneling. 
Displays the current configuration. 
Displays the last 20 commands entered during the 
current CLI session. 
Displays tunnel accept status. 
start character <control> 
Sets the accept mode start character. The character 
may be input as text, control, decimal, or hex. A 
control character has the form <control>C. A 
decimal value character has the form \99. A hex 
value character has the form 0xFF. 
tcp keep alive idle time <milliseconds> 
Sets the TCP keep alive idle time. This is the initial 
keep alive timeout. <milliseconds> = timer value, in 
milliseconds. 
tcp keep alive interval <milliseconds> 
Enables TCP keep alive for accept mode tunneling 
and sets the value for timeouts subsequent to the 
initial timeout. <milliseconds> = timer value, in 
milliseconds. 
tcp keep alive probes <number> 
Sets the number of TCP keep alive probes. 
<number> = number of TCP keep alive probes. 
Stores the current configuration in permanent 
memory. 
accept (tunnel-accept:7) level commands 
Enables the tunneling server to always accept 
tunneling connections. 
accept mode any character 
Enables the tunneling server to accept tunneling 
connections only when a character is received 
through the corresponding line (serial port). 
Disables accept mode tunneling. 
accept mode modem control asserted 
Enables the tunneling server to accept tunneling 
connections when the modem control pin is 
asserted. 
accept mode modem emulation 
Enables modem emulation for accept mode 
tunneling. 
accept mode start character 
Enables accept mode tunneling when the 
configured start character is received on the line. 
aes decrypt key <hexadecimal> 
Sets the accept tunnel AES decrypt key with up to 
16 bytes. Each byte is represented by two adjacent 
hex digits. Bytes may run together or be separated
