a) Incoming Connection 
Never Accept Incoming 
Rejects all external connection attempts. 
Accept with DTR Active 
Accepts external connection requests only when the DTR input 
is asserted. Cannot be used with Modem Mode.  
Always Accept 
Accepts any incoming connection when a connection is not 
already established. Default setting. 
b) Response 
Character Response 
A single character is transmitted to the serial port when there is a 
change in connection state: 
C
 = connected, D = disconnected, N = host unreachable.  
 
Single character mode specifies the character response. The IP 
address of the host connecting to the unit displays when the unit 
is in verbose mode. This option is overridden when the Active 
Start Modem Mode
 or Active Start Host List is in effect. 
Default setting is Nothing (quiet)
c) Active Startup 
No Active Startup 
Does not attempt to initiate a connection under any 
circumstance. Default setting. 
With Any Character 
Attempts to connect when any character is received from the 
serial port. 
With DTR Active 
Attempts to connect when the DTR input changes from not 
asserted to asserted. 
With a Specific Start 
Character 
Attempts to connect when it receives a specific start character 
from the serial port. The default start character is carriage return. 
Manual Connection 
Attempts to connect when directed by a command string 
received from the serial port. The first character of the command 
string must be a C (ASCII 0x43), and the last character must be 
either a carriage return (ASCII 0x0D) or a line feed (0x0A). No 
blanks or space characters may be in the command string. 
Between the first and last command string characters must be a 
full or partial destination IP address and may be a destination 
port number.  
 
The IP address must be in standard decimal-dot notation and 
may be a partial address, representing the least significant 1, 2, 
or 3 bytes of the remote IP address. The period is required 
between each pair of IP address numbers. 
 
If present, the port number must follow the IP address, must be 
presented as a decimal number in the range 1-65535, and must 
be preceded by a forward slash (ASCII 0x2F). The slash 
separates the IP address and the port number. If you omit the 
port number from a command string, the internally stored remote 
port number starts a connection.
