Router 1720: Networking problem

Hi,
I have a router Cisco 1720
I connect the router to my workstation(Workstation#1) using the console cable
I copied the current configuration (Please see the attachment)
+1) From the configuration, I know ..
+2) The IP address of the Router is “ 192.168.254.1” and the subnet mask is “255.255.255.0”
The goal: I want to connect this router to my workstation(Workstation#1) using the cross-over cable
The things that I did:
+3) On my workstation(Workstation#1):
      +i) Go to the TCP/IP setting
      +ii) Give the IP : 192.168.254.2
      +iii) Subnet-mask : 255.255.255.0
      +iv) Default Gateway: Blank
      +v) DNS: Blank
+4) Testing the connection (between Workstation#1 and Workstation#2)
      +i) I use another computer (Workstation#2)
      +ii) The TCP/IP setting of workstation#2
            +a1) IP address: 192.168.254.1
            +a2) The Subnet-mask: 255.255.255.0
     +iii) I connect workstation#1 and workstation#2 with cross-over cable (I can see the “blinking lights” both at RJ45 ports of both workstations)
      +iv) I can ping successfully workstation#2 (192.168.254.1) from workstation#1 (192.168.254.2) and vice versa

+5) Now, I want to connect my workstation (Workstation#1) with the Router 1720 using the cross-over cable
      +i) I connect the cable, but I did not see “any blinking” at both RJ45 ports either at Workstation#1 or Router 1720
      +ii) But I continue with creating the connection:
            +a1) Open the Hyperterminal
            +a2) Host address: 192.168.254.1
            +a3) Port #: 23
            +a4) Connect using: TCP/IP (Winsock)
      +iii) I got the error message: “unable to connect to 192.168.254.1 port 23”

Any help?

@aarie & @ iammorrison:

1) I tried "Straight throuhg cable"
- Result: It is the same as above (It does not work)
2) I did not see "any blinking lights" at RJ45 ports either at Router or Workstation#1
3) @iammorrison: I connect to 10/100 Ethernet Port at the router (There are 3 ports: Console, AUX and 10/100 Ethernet Port; all ports are RJ45 ones)
4) When I did "ipconfig" at workstation#1; the result: "media disconnected"
5) When I tried to ping "192.168.254.1"; Result: "Destination host unreachable"
6) When I tried to ping "192.168.254.2"; Result: "Destination host unreachable"

Conclusion:
1) It seems that the Router is DEAD ....
2) Workstation#1 cannot DETECT it at all ...
3) (But Workstation# 1 can connect to workstation#2 Perfectly)
4) I believe there is "something" in the router configuration that we should add?

Any help?

thanks,
tjie

@iammorrison
I did the followings: (as per your direction)
enable
conf t
int fast 0/0 (or fast 0/1 if there is a WIC installed)
no shut
Then, I did restart the router “reload”
When I did CHECKING:
+1) The Result is still THE SAME; I cannot connect to the Router (Using Telnet; port# 23)(Either using Straight or Cross-over cable)
+2) When I do “Show Run” and copy the above configuration; I cannot find the wording “NO ShUt”; is it the SIGN that the Router is not able to do the modification anymore?
