Subject:   silo overflow!? w/ 16550s!

I have a system with 4 16550 capable serial ports. All run on their own 
IRQ and I/O address. Two of the ports are internal modems [a 14.4 and a 
28.8] and card has another 2 ports each connected to 28.8s. All ports [as 
above] are 16550 UART'd.

When one connection is open full blast [a slip] there is no problem. The 
minute I try to use kermit to dial out to a local system for giggles, or 
even another modem on the same machine I get :

system /kernel: sio1: 1 more silo overflow (total of 10)  for example.

I really hope this has more to do with some setup problem that I can fix 
than some fundamental hardware problem that I can't circumvent!

Any ideas/insight etc would be _greatly_ appreciated!

-Jerry.
