Long Description:Setting up a digitizer on an NCD X-terminal

Solution:
____________________________________________________________________________

Connecting a digitizer to an NCD X-Terminal:

The X-Terminal is assumed to be running NCD88K 8-bit Color local clients server
version 2.4.7

Note: This is important, because with this version, the auxilliary port has
been identified as port address 87 by NCD.

Go into the configuration file for the NCD and add the following line:
seriald-tcp-port=87

Next, go into the setup menu for the NCD.
Click on `Serial Parameters'
Change `Use Port For' to Printer Daemon

You must have the following files located on the host platform, and they must
have been compiled for the host platform:
nd
tcpcon

NOTE: Be sure these are the only versions on the host platform, or put in the
path that points to the nd or tcpcon verison you want to run.  To check where
you are running nd and tcpcon from type `which nd`, and it will give you the
path.

Go to the directory which contains the nd and tcpcon files.
Type the following:
nd -\& -r tcpcon -l /dev/ptypf ferengi 87

Note: /dev/ptypf can be substituted for any legitimate device with the correct
permissions, but do note that it is the pseudo device for ttypf.  It must be
the pseudo name for the device.
      ferengi is the node name of the x-terminal, and the IP address may be
substituted here.
      87 is the address for the auxilliary port on the x-terminal and must be
87

The nd command sets up a daemon to run the tcpcon.
The tcpcon sets up the re-routing of /dev/ttypf to accept from ferengi's aux.
port 87.  This command runs in the background and must be killed to stop it.

This setup was tested using a Drawingboard II on an NCD 19C x-terminal with the
following host platforms:

Sun Sparc 2, SunOS 4.1.2
IBM RISC 6000, AIX 3.2
DG Aviion, OS 5.4.1
