Serial connection confusion

This is in packet tracer.

I was working on a lab someone did and there is a serial connection between two routers /w hdlc encapsulation.

R1 <-> R2 <-> R3

These two talk fine
R1:
Serial0/0/0 is up, line protocol is up (connected)
Hardware is HD64570
Internet address is 10.1.1.1/30
MTU 1500 bytes, BW 1544 Kbit, DLY 20000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation HDLC, loopback not set, keepalive set (10 sec)

R2:
Serial0/0/0 is up, line protocol is up (connected)
Hardware is HD64570
Internet address is 10.1.1.2/30
MTU 1500 bytes, BW 1544 Kbit, DLY 20000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation HDLC, loopback not set, keepalive set (10 sec)

These below two do not talk.

R2:
R2#show int serial 0/0/1
Serial0/0/1 is up, line protocol is down (disabled)
Hardware is HD64570
Internet address is 10.2.2.1/30
MTU 1500 bytes, BW 1544 Kbit, DLY 20000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation HDLC, loopback not set, keepalive set (10 sec)

R3:
R3#show int serial 0/0/1
Serial0/0/1 is up, line protocol is down (disabled)
Hardware is HD64570
Internet address is 10.2.2.2/30
MTU 1500 bytes, BW 1544 Kbit, DLY 20000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation HDLC, loopback not set, keepalive set (10 sec)
Last input never, output never, output hang never



As far as I can tell they are configured the same, but one works ans the other doesn't.

So, any ideas on what is going on?

Thanks,

Bill
 
I figured out my problem, you can disregard the above question.
