I was using 4K blocks (which fits in an inter-process pipe. I don't know
how big the network buffer is).
In any case, these processes should be able to saturate the 16KByte/sec
maximum (highly optimistic) throughput of an ISDN line. If they can't then
something is drastically wrong with either the PPP drivers, serial drivers, or
the BSPro (which has been hinted at in the past).
