	Hello everyone,


	Having recently acquired a pair of v.fast modems, I would like
to implement SLIP on my DEC 5000/125.  However, after running remote logins
(not SLIP, just std. logins) for a while, a couple of us here have noticed
what appears to be an over-run condition occuring on the DEC 5000.  The
session manager on the machine notes something called a "silo error" or 
"silo overflow" (pardon me, I don't remember which).  We think that it may
be attributable to an overflow of the DUART on the DEC 5000, but we're not
certain.


	Thus, I have the following questions:


	(1) Has it been documented that the "default" maximum *effective* 
	    DUART throughput of the DEC 5000 is limited, and if so, to what
	    value (we stop having problems at 9600)?

	(2) If (1) above is generally true, is there then a means of
	    increasing the *effective* throughput to the DUART?



	BTW, I'm aware that the DUART hardware will run up to 204000 baud.
It appears that the machine's software is not properly set up to support that
high a data rate to/from the DUART.


	Thanks,


	Jim
