Cisco 2503 routing problems

I have two cisco 2503's (I know, I know, "Update for cripes sakes!") and am having problems routing between two of my serial interfaces. I am using class "C" addresses of 192.168.0.1 and .2 255.255.255.0 between them (testlab with DCE/DTE cables). I have "no shut" the interfaces and setup "clock rate 64000" on the DCE side. The paste below is all I can get out of it though:

Serial1 is down, line protocol is down

Hardware is HD64570

Internet address is 192.168.0.2/24

MTU 1500 bytes, BW 64 Kbit, DLY 20000 usec, rely 255/255, load 1/255

Encapsulation HDLC, loopback not set, keepalive set (10 sec)

Last input never, output never, output hang never

Last clearing of "show interface" counters never

Input queue: 0/75/0 (size/max/drops); Total output drops: 0

Queueing strategy: weighted fair

Output queue: 0/1000/64/0 (size/max total/threshold/drops)

Conversations 0/0/256 (active/max active/max total)

Reserved Conversations 0/0 (allocated/max allocated)

5 minute input rate 0 bits/sec, 0 packets/sec

5 minute output rate 0 bits/sec, 0 packets/sec

0 packets input, 0 bytes, 0 no buffer

Received 0 broadcasts, 0 runts, 0 giants, 0 throttles

0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort

0 packets output, 0 bytes, 0 underruns

0 output errors, 0 collisions, 142 interface resets

0 output buffer failures, 0 output buffers swapped out

0 carrier transitions

DCD=up DSR=up DTR=down RTS=down CTS=up

Thank you for any assistance,

Lost in routing hell

Re: Cisco 2503 routing problems

Can you paste output of "show controllers serial 0" on either ends.

Sure can, I'd be glad to and here they are for all serial links/each router:
