help with config for remote router

The router config here is the main network the remote site (router died, and no config is available cisco 2500 series) The old router at the remote site had two serial ports and one LAN (aui) port.

Need to setup a new router at the remote site. Its going to have a WIC card in it. The encapsulation is HDLC what configs are needed on the remote side for the point to point 1T to work.

LAN ip 192.168.20.10

WIC ip (?) 192.168.200.2 255.255.255.0 [the 192.168.200.1 is the main server ip to this location]
