USING THE M208’S ADDITIONAL OPTIONS: TCP/IP Options 139
To utilize this feature, you need to:
1 Look into the npscramble.c source code for a variable called SR_KEY. This con-
tains a four digit hexadecimal value to be used as the descrambling key on the
M208.
2 Log into the M208 as root user and set this value as the key. Enter:
set sysinfo descramblekey
key
3 Set descrambling on in the model you are utilizing. Enter:
set model
modelname

5 Incorporate npscramble into your print setup on your host. Scrambling can be set
within npr.if or added to the command line when printing.
cat test.txt | npscramble | rsh spike lp -d d1prn
where test.txt is piped through npscramble for scrambling and then sent for
printing on the M208 spike’s destination d1prn.
Please see Host Software on page 31, Printing Via the Spooler on page 44, and set
model on page 110.
Using the Terminal Server Capabilities
The M208’s built-in command set includes telnet which allows the unit to act as a ter-
minal server as well as a M208. The M208’s terminal serving capabilities can be used
in a number of ways including connecting a terminal to a network or using a terminal
as an output device.
To use the M208’s terminal serving capabilities to connect a terminal to the network,
you need to:
1 Physically attach the terminal to one of the serial ports on the M208.
2 Press the <Break> key and at the prompt, type in the IP address of the host that
you want to connect to.
3 Login to the host.
