Hello,

THe pppd works for me for a long time.  However,  I found out that there
is a little problem of it.  The error is

================error=============
pc135# ping b1
PING b1 (208.151.73.70): 56 data bytes
ping: sendto: No buffer space available

ping: sendto: No buffer space available
ping: sendto: No buffer space available
ping: sendto: No buffer space available
ping: sendto: No buffer space available
ping: sendto: No buffer space available
=========================================

Then I have to discount it and reconnect the line.  Any idea ?  I enclosed
all the files I use for your help.  Thanks.

Clarence
