PPP Problems over Async cct

When using PPP over a async link (using the aux port) the PPP process gets past the LCP negotiation then stops during the NCP negotiation. The IPCP remains listening and no further conversation between the two ends takes placeThe two devices at the end of the circuit are 2600 series routers. Using SLIP instead of PPP provides no joy...

Any ideas ???
