My PPP stopped working...

  Beginning yesterday I'm having problems establishing a ppp connection
under linux. This is going from my machine at home to one on my desktop in

The sequence now looks like:
[root@doc scripts]# ./ppp-on
Serial connection established.
Using interface ppp0
Connect: ppp0 <--> /dev/ttyS3
sent [LCP ConfReq id=0x1 <asyncmap 0x20a0000> <magic 0x470d2272> <pcomp>
rcvd [LCP ConfReq id=0x1 <asyncmap 0x20a0000> <magic 0x470d2272> <pcomp>
sent [LCP ConfNak id=0x1 <magic 0xf9cf15a1>]
rcvd [LCP ConfNak id=0x1 <magic 0xf9cf15a1>]
sent [LCP ConfReq id=0x2 <asyncmap 0x20a0000> <magic 0xb110bf65> <pcomp>
rcvd [LCP ConfReq id=0x2 <asyncmap 0x20a0000> <magic 0xb110bf65> <pcomp>
sent [LCP ConfNak id=0x2 <magic 0x2e1c30>]
rcvd [LCP ConfNak id=0x2 <magic 0x2e1c30>]

lotsa more of those... and then

Serial line is looped back.
sent [LCP TermReq id=0xb "Loopback detected"]
rcvd [LCP TermReq id=0xb "Loopback detected"]
sent [LCP TermAck id=0xb]
rcvd [LCP TermAck id=0xb]
Connection terminated.
Connect time 0.1 minutes.

This same setup in windows establishes a ppp connection, and I'm dialed
into my desktop right now using minicom, so the connection works up until
the estiblishment of the ppp.

Where does this "loopback detected" come from? I can't really see what
could have changed.
