I haven't seen any problems with the clock on my 4/260.  I have been 
using Netscape 2.0b4 (without the "hanging" problems described by Greg, 
excelt when I use Java, and it then seems to be related to the fact that 
it consumes vast quantites of VM...), and I've been using the 
keyboard/mouse (obviously, but that's actually serial activity) and ttya 
as the console for my terminal server.  Granted, it's not a heavy use of 
the serial port, but it is serial activity.

Hmm ... I can't seem to find this constant...though, I remember a 
discussion about it...

Well, I'll do that I can, but darn if this doesn't sound bloody weird :-)
