Accessing the admin port from a Unix Host

Issue:

This example shows how to administer a JetStream, LanStream, or CS9000 server from a unix host via the Admin port.
The unix host COM port is used to connect to the Admin port but other types of serial port (SX, RIO, etc) can be used with the appropriate cable. The cu configuration shown is for SCO OpenServer 5.

Solution:

Cables

Here are the two common cable pinouts used to connect a PC DB9 COM port to the JetStream/LanStream admin port.

Admin PC
DB25 DB9
7 5
2 3
3 2

Admin PC
DB9 DB9
5 5
3 3
2 2

Unix Setup

To setup the cu link for SCO OpenServer 5 add a device line to the /usr/lib/uucp/Devices file.
E.g. for COM 1
Direct tty1a – 9600 direct

To access the Admin port connect the cable and run the cu command.
E.g.
cu –l tty1a
You now have direct access to the admin port.

To access the admin port and record the port output use the following command.

cu –l tty1a | tee
E.g.
cu –l tty1a | tee /tmp/xstream.log
