The default display height for XRPi is 25 rows, which matches
the format used in DOS XRouter.
However, you may find that with just 25 lines, the status
windows are too cramped, and console pages are too short for
comfort, in which case you may expand the display by using the
ROWS directive at the start of XROUTER.CFG. For instance, for
a 50-row display use ROWS=50.
Depending on your screen resolution and "terminal window"
settings you may be able to use 60 or more rows, however some
display adaptors won't allow you to go much beyond 40 rows.
It is better to start with a low figure and increase it 10 at
a time until you find the limit for your adaptor. Beyond the
limit, the display will either break up or behave oddly.
