Subject: MEX TIMEBASE parameter

Regarding the query by Mike Ryan regarding the MEXPAT TIMEBASE parameter, I 
don't now what this does, and would be interested to know (in fact MEXPAT
does not seem to be very fully documented anywhere.  There is a file
MEX-BUFF.LBR, but I think that it only discusses the buffers part of MEXPAT).
I am not sure what exactly is meant by "buffer overrun" in this context.  MEX
has a "modem port queue" which can fill up when incoming data rates are high.
I have experienced this problem when running at 9600 baud and avoided it by 
setting STAT QUEUE OFF and having an external buffer with the ability to 
exercise flow control.
