From ec3b548646d8739c35e2a66379e921b3438fe367 Mon Sep 17 00:00:00 2001
From: Fritz Elfert <felfert@to.com>
Date: Tue, 22 May 2001 21:56:49 +0000
Subject: - Added support for extended sequence numbers (incoming only) -
 Changed the behavior on initial connect to support the Clipboard-Server   and
 to meet the doc in http://www.thouky.co.uk/software/psifs/plp.html:   All
 services except SYS$RFSV now perform registration and connect is   done when
 the Psion returned RegisterAck. Then the connect can use the   service name
 as presented by the Psion's RegisterAck.
