Turning off LocalTalk is very ill-mannered.  Other processes that are using
the AppleTalk protocol stack will be upset and extremely unhappy.  To wit:
(IM II-275) "Since other co-resident origrans may be using AppleTalk, it's 
strongly recommended that you never use this call.  MPPClose will completely
disable AppleTalk; the only way to restore AppleTalk is to call MPPOpen again"

To detect if the printer port is available, try opening the serial driver
for port B.  If portInUse is returned, then port B is in use by someone 
other than the standard serial driver.
