Terminal Server Setup

I have a Cisco 2610 router (older model, not the XM version) with a 4- Port Async/Sync Network Module (NM-4A/S). I'm trying control a serial device through an IP connection to the router.

I am able to get a connection from the router to the serial device, but I cannot connect from a PC to the router at 192.168.21.110 : 2033 (or 4033 or any 20XX or 40XX ports). For some reason I can connect to port 80 which I though was kind of strange.

Any help would certainly be appreciated.

Chris

You need 'physical-layer async' on the A/S serial interface, to put it into async mode. Then on the corresponding line, configure this for a "console server" application:

line 33 no exec transport input telnet modem dtr-active

Then you can telnet to TCP port 2033 to talk out this line to the async device.

Regards,

Aaron

Aaron,

I followed your directions but still can't connect. Here is the results. The Serial 1/0 line is now down. I have it connected to a Hyperterminal session with the settings 9600, 8 databits, No parity, 2 stopbits, Hardware flow control.

Chris,

In what sense can you not connect?

Note that interfaces are irrelevant from the standpoint of a "terminal server" setup. What counts are lines not interfaces. (Except in that you need to configure an A/S interface for "physical-layer async" if you want to do async.)

Configuring a Terminal/Comm Server

Basically, just do a "show line " to make sure that the line is in the right state.

Then telnet and you should be talking out that line.

If it doesn't seem like this works, then you've got the wrong speed, or hw flow isn't right for you, or you have a bad cable etc.

Regards,

Aaron

Aaron,

Nevermind.

I got into line 34 (port 2034). Must be something wrong with line 33 as I set them up the exact same way.

Thanks for your suggestions, they really helped.

Helpful tips for async connections:

Use the 'clear ' and/or 'disconnect ' commands to reset the lines. The error message you saw when trying to connect sometimes indicates the line is used or hung.
