 Please submit some relevant logs.  Check out
 
   http://www.FreeBSD.org/FAQ/userppp.html
 
 for some hints on how to generate some useful information.
 
 Also, be careful.  It's likely that the ``Interrupted system call'' 
 is an error resulting from a decreased ``redial'' timeout forcing ppp 
 to attempt to re-open the port too quickly after failure and blocking 
 for more than 1/10th of a second.  It is very unlikely that this has 
 anything to do with the actual problem... the log files should reveal 
 this.

 Hi,
 
 Thanks for your mail.  I haven't included it since it contains 
 passwords etc, but I've cc'd this to freebsd-gnats for tracking 
 purposes.
 
 It seems that your ISDN link is synchronous - ie, the ``async'' layer 
 that data passes through at the link level is not required.  This is 
 evident by comparing the data you're receiving at the async level 
 (async logging) with the data that's being sent at the hdlc level 
 (which is then escaped etc. at the async level).  Ppp can support this 
 in theory, but in practice it's horribly broken and I don't have the 
 (hardware) resources to even attempt to fix it.
 
 However, all's not lost.  Joerg has done some work on synchronous 
 ppp, but you'll need to use the kernel ppp implementation.  The 
 sppp(4) man page describes how to go about getting things up and 
 running.
 
 I'm afraid I know very little about kernel ppp, so if you run into 
 difficulties, your best bet is to ask some questions on
 
   freebsd-questions@FreeBSD.org
 
 Sorry I'm not more help.
 
 Cheers.
