Terminal server

[Sunil_uk]

Can some one guide me to setup a terminal server DEC700 on TCPIP network and to drive a serial display device on terminal server port PORT_01.

Presently it is working on LAT.
The application program takes the logicals and drive the display.
following def is used in LAT startup to enable the lat port
lcp set port LTA0201: /node=tght01(host name of the terminal server) /port=port_1
Is there any simillar def for enableing it on TCPIP address.

Hi Sunil,

This is the minimum you have to do.

On the DS700:-
LOCAL> set priv
password>
LOCAL> change internet address ip_address
LOCAL> change internet mask 255.255.255.0 (e.g.)
LOCAL> change telnet listener 2001 port 1 enable
LOCAL>

On the OpenVMS system:-
TELNET> create_session ip_address 2001
%TELNET-S-CRSES, Session created on TNAxx
TELNET> exit

$ sho dev tnaxx

Device Device Error
Name Status Count
TNAxx: Online 0

You should be able to use the TNAxx created.

Thanks and regards.

Though I have set the telent listener port 2001 to port 1, the show port 1 still shows default protocol as LAT.

I am able to ping after configuring the IP address.

I did the following

Local>Change telnet listener 2001 port 1 enabled

Hi Sunil,

After you set the telent listener port 2001 to port 1 and enabled it, you can see the telnet listener with the following.

LOCAL> show telnet listener 2001

You can connect to this port remotely from a host like the following.

$ telnet ip_address /port=2001

If port 1 is connected to a display, then anything you type will be displayed on the device connected to port 1.

If you establish the connection using the method in my last reply, like

On the OpenVMS system:-
TELNET> create_session ip_address 2001
%TELNET-S-CRSES, Session created on TNAxx
TELNET> exit


Then you can use the following DCL to write to the device TNAxx.

$ Open/read/write chan TNAxx:
$ write chan "testing"

The word testing should be sent to the display connected to port 1.

Whenever you have a connection to telnet port 2001, you can check the status and the counters of port 1 by

LOCAL> show port 1 status
LOCAL> show port 1 counter

Remember to close the channel.

$ close chan

Remember to free the telnet listener 2001 by the following.

TELNET> delete xx

Thanks and regards.

Thank you all for the guidence. I could configure the port successfully. This Decserver port i will using perminantly to connect a display unit, which displays some numeric values send by my srever. There is pascal program which already running which uses LAT presently (device name used LTA0201). I should be able to replace this device bt TNA1, which I have created from the telnet session.Any suggetion on this?.

Thanks

Hi Sunil,

It may be better to use a logical name inside the program. Then define the logical to point to the created TNAxx: device.

Thanks and regards.

Do I need to create a different TCPIP socket
inorder to establish the link or the telenet session which I have cretaed (TNA1:) will take care of the tarnsmission?.

I need to create thsi terminal device in another theree more servers pointing to same port on the same terminal server.is it possible?.

When I tried it was giving time out error.

thank you

Hi Sunil,

The telnet session created will take care of the transmission. You just use the device TNAxx as a normal terminal device.

You can connect to the same port on the same terminal server from different systems, but one at a time. This means that once a system has connected to port 1 of terminal server A, the other system will have to wait until the original telnet connection has terminated. In order words, you cannot have multiple simultaneous telnet connections to the same port of the same terminal server.

Hope the above is clear.

Thanks and regards.
