What specific issues are you having with your configuration.
What hardware/WIC's do you have installed in your TS.

If you have an NM-8A or NM-16A module, verify the following are setup on your terminal server

1. Create a loopback interface with an IP address <since this virtual interface will always be available>

2. Issue the "show line" command to identify you async ports.  They will be listed as (TTY) with a default speed of 9600

Tty Typ     Tx/Rx    A Modem  Roty AccO AccI   Uses   Noise  Overruns   Int
     0 CTY              -    -      -    -    -      0       0     0/0       -
     2 TTY   9600/9600  -    -      -    -    -     29       0 11108532/0     Se0/1
     3 TTY   9600/9600  -    -      -    -    -     29       0 14644700/0     Se0/2
    65 AUX   9600/9600  -    -      -    -    -      0       0     0/0       -
*   66 VTY              -    -      -    -    - 131589       0     0/0       -
*   67 VTY              -    -      -    -    -   2266       0     0/0       -
    68 VTY              -    -      -    -    -     23       0     0/0       -
    69 VTY              -    -      -    -    -      0       0     0/0       -
    70 VTY              -    -      -    -    -      0       0     0/0       -

3. Create an ip host table to connect to your device.  Using the information above an example would like the following:

Line 2 is the first available port that can be configured (Se0/1)
Line 3 is the next available port that can be configured (Se0/2)

     ip host Unix1 2002 <interface loopback IP address>
     ip host Unix2 2003 <interface loopback IP address>

4. Line 2 3 configuration:

     line 2 3
       session-timeout 20
       no exec
       exec-timeout 0 0
       transport preferred telnet
       transport input all
       speed <whatever you need it to be or leave at 9600 default>

5. To test type the host name <Unix1> at the router prompt or type telnet <interface loopback IP address> 2002

Let me know how far you get or if you're past this point.
