Hi,

getting a different result here... see this log (ipaq is connected via
irda)

ipaq_at_barney ~/dev $ telnet maggie 9999

Connected to maggie.

When I plug in the serial cable, activeSync terminates the irda
connection, but as you can see, when i reconnect (via irda) GPLR(4) is
indeed set to 1, as Andrew predicted.
