PPP connection from Pocket PC to Linux fails

I am trying to create a PPP link between a PocketPC (client) and a
linux pppd server but this keeps failing at the same point.

I have created a dial-up connection on the PocketPC using RAPI
provisioning. Here is the xml for that:

***************************************************************************­
****************

After sending the last ConfAck the Pocket PC displays the message "the
answering modem has disconnected" and terminates the link even though
the link is obviously still live (the pppd server keeps sending
requests).

I also tried disabling CCP (used the noccp option in the pppd option
file). The negotiation completed successfully, but the PocketPC
immediately displayed the message "the answering modem has
disconnected" and the link went down on its side. The server, however,
does not detect this and the server side stays open indefinitely (no
further connection attempts possible).

Does anyone have any ideas what could be the problem here? I do not
see anything strange in the PPP log.

Also, is there an equivalent log on the Pocket PC? Can it be read
somehow?
