Network Write Delay using PPPD

[Mike Siers]

Hi,
I am using the i386/pc586 BSP with the latest snapshot.  My code
is using the standard pppd task to establish a network connection.
The ppp connection gets established and I can create a socket and 
connect to my server test application.  

The RTEMS client code will write a block of data every time it 
receives some data over the socket.  The problem that I am seeing 
is that the client write seems to be getting delayed.  And the
delay keeps getting longer after each successive write.  After four 
writes, the delay is about 90 seconds!  I have turned off the pppd
compression options.

I added some debug statements to the pppd code.  Basically it looks
like the pppoutput function is getting called immediately but the
modem_sendpacket function call gets delayed.

Has anyone seen this problem before?  Any thoughts or suggestions
would be greatly appreciated.

Thanks
Mike Siers
