Silo overflows occur when the remote end (modem) is sending data
	faster than the mac can keep up. They result in dropped packets
	which will need to be retransmitted.

	Try reducing the pppd serial speed - you may actually see faster
	transfers as it will no longer have to be coping with dropped
	packets.
