Hello,
Configuration of 3700 router as a terminal server is similar to the 2500
configuration. The only difference will be the line numbers (which depends
upon the module you are using and where you have inserted it).

If you issue "show run" it will list the terminal line numbers in the
configuration. Then you can follow the above procedure for remaining
configurations.
Hope this helps.
Regards,
