The problem with PPP is that no data is transmitted or received from the
serial device. Data input and output is handled by the pppintr function.

In the 1.1 kernels this routine was always called in dosoftints in 
irqhandler.c.

Looking at the 1.2 source this routine is only called if the NETISR_PPP 
bit of the variable isr is set. My _guess_ ios that when pppd has some 
data to transmit or when serial data is received this flag is not 
set. 

This is all based on examination of the source code. In the next couple 
of days I am hoping to download the current kernel sources to see if this 
is the problem.
