Is it possible to easily detect if an exit is already open, and then not send the open command.

Speciffically there is an exit in sneezy that has the same command to open as close "pull branch" so if it's open, I close it, and have to then open it again.

The exit line dosn't show exits that are closed.

eg
Exits [N S E] - with the door to the west closed.
Exits [N S E W] - with the door open.

Secondly, I have to raise a port cullis, my work around is to set the door name to "; raise port" and I always get the error (from the mud) open what. Any fresh ideas.

I suggest using the door name field for special exits like the branch and portcullis. By changing the open commands in the "Strings and Doors" page of the mapper configuration to:
#IF ("%2"!="") {%2} {open %1}
you can simply enter the appropiate command as the door name.

Detecting whether a door is open is extremely simple, because your mud simply leaves that exit out of the when when it is closed.
#TR {^Exits ~[(*)~]$} {#VAR ExitLine %replace("%1"," ","|"}
now we revisit the open command within the mapper and see if the exit was present when entering the room.
#IF (%ismember(%1, @ExitLine)=0) {#IF ("%2"!="") {%2} {open %1}}
