DECserver 90M

When using the DECserver 90M in combination with the backplane of the MultiStack System (DETRX or DETAX backplane), the Position Identifier Dail on the rear of the backplane should be set to the Agent position. If not, the UTP port (10baseT) will not be operational (may also apply to the thinwire connection, not tested). The MultiStack System Installation and Configuration guide doesn't explicitly mention this although it does mention that a management agent in the stack is assigned an IP address.

DECserver 300

Configuring DECserver 300

Enabling Command History on Port

> DEFINE PORT <port-nr> TYPE ANSI

Network Configuration

> DEFINE INTERNET ADDRESS <ip-addr>
> DEFINE INTERNET NAME RESOLUTION DOMAIN <domain>
> DEFINE INTERNET NAME RESOLUTION MODE ORDERED
> DEFINE INTERNET NAMESERVER <ns-name> ADDRESS <ns-addr>
> DEFINE INTERNET GATEWAY <gw-addr>

> SHOW INTERNET

Reboot DECserver

> INITIALIZE				(reboot, 1m delay)
> INITIALIZE DELAY 0			(reboot immediately)
> INITIALIZE DIAGNOSE FULL COUNT 2	(reboot, twice thorough self-test)

Setup Telnet Listener for getty Behind MMJ Port

Telnet listener on (TCP/IP) port 2002; serial cable on MMJ port 2 connected to serial port of some other system running a getty on that port.
> DEFINE TELNET LISTENER 2002 PORTS 2
> DEFINE TELNET LISTENER 2002 CONNECTIONS ENABLED
> DEFINE PORT 2 ACCESS DYNAMIC
> DEFINE PORT 2 DEFAULT PROTOCOL ANY
> DEFINE PORT 2 STOP BITS 1
> DEFINE PORT 2 AUTOBAUD DISABLED
> DEFINE PORT 2 SPEED 9600
> DEFINE PORT 2 TYPE ANSI
> DEFINE PORT 2 TELNET SERVER NEWLINE FROM HOST <CR>
> DEFINE PORT 2 TELNET SERVER NEWLINE TO TERM <CR>

> SHOW TELNET LISTENER 2002
> SHOW PORT 2
> SHOW PORT 2 TELNET CLIENT
> SHOW PORT 2 TELNET SERVER
> SHOW PORT 2 SESSIONS STATUS    (only if connected)
However, when opening a telnet connection to port 2002 on the DECserver, the getty login prompt appears but characters are echo'ed twice.

Enable Local Connection from one Port to Another

Define a LAT service "LPORTS" which enables local connections to be established between ports 2 to 16.
> DEFINE SERVICE LPORTS CONNECTIONS ENABLED
> DEFINE SERVICE LPORTS IDENTIFICATION "Local port access"
> DEFINE SERVICE LPORTS PORTS 2-16 ENABLED
> DEFINE PORT 2-16 DEFAULT PROTOCOL LAT
> DEFINE SERVER ANNOUNCEMENTS ENABLED
Enabling server announcements doesn't appear to be necessary for accessing ports locally.
> SHOW SERVICE LOCAL
> SHOW SERVICE LOCAL STATUS
> SHOW PORT 2

> CONNECT LAT LPORTS PORT PORT_2
"LAT" may be omitted if it's the default protocol for the port. Also note that you use the name of the port when connecting, but its number when defining the service.

DECserver 700

Setup Telnet Listener for Printer Behind RJ Port

Not sure whether this is the proper way to do it, but the command list below did enabled me to make hardcopies on a Digital LA30N Companion dot-matrix printer (on serial port 8). Send text file (UNIX line-endings) to TCP port 2008.
> SET TELNET LISTENER 2008 PORT 8 
> SET TELNET LISTENER 2008 CONNECTIONS ENABLED

> SET PORT 8 TELNET SERVER NEWLINE FROM TERM <LF>
> SET PORT 8 TELNET SERVER NEWLINE TO HOST <CRLF>
> SET PORT 8 TYPE HARDCOPY
> SET PORT 8 ACCESS REMOTE

> SET PRINTER la30n AUTOCR ENABLED
> SET PRINTER la30n HEADER DISABLED
> SET PRINTER la30n TRAILER DISABLED
> SET PRINTER la30n CONNECTIONS ENABLED
> SET PRINTER la30n IDENTIFICATION "Digital LA30N Companion"
> SET PRINTER la30n PORTS 8 ENABLED
