Hi out there,

I am working now for two weeks again with 386bsd, and almost
everything is working fine. But there are still two unresolved
Problems.

1. COM-ports: I am using the COM-Multiport-Driver and 16550-USARTs.
	Im still getting SILO-Overflow's at 38400 Baud. Due to the 
	fact that I am using a 14400 Baud Modem with V42bis, I would
	want to use the fastest possible COM-Speed. 

	Question: Is there a driver (or driver-configuration) that will
		work at these speeds? What will happen if i'd change
		FIFO_TRIGGER_4 to 8 or 14 in the Multiport-driver.
		Are the lost chars due to getting too many interrupts,
		or is the response-time to a given interrupt to long?
		Will a COM-Driver that uses CTS/RTS do any better?

2. SLIP: (or even better routing between SLIP and WE0)
	My machine is setup to use an WD8003E-Card as an Ethernet-
	interface. One other PC is connected via SLIP. Each of the
	interfeaces works fine. But the requests dont get routed
	towards the different networks (Etherent, SLIP). The route-
	Manualpage states that this is done automaticly. I suspect
	that I am doing something wrong. Would someone be so kind
	and explain to me what I have to do to get the routing to work?
	Thanks!

For the first Question I think I should add that the Machine is NOT
heavily loaded, has 16 Megs of RAM and an 486/33Mhz.


Thanks a lot for not getting tired in answering dumb questions.
