// Rev 2.1 19 Sep 1994 11:09:28 RICHARD
// Deleted the port name parameter to the YieldToStatusWindow function.
//
// Rev 2.0 23 Aug 1994 13:54:10 RICHARD
// Changed references of "FAR *" to type definitons of LP...
// Changed references of HANDLE to PORTHANDLE
//
// Rev 1.10 11 Nov 1993 11:08:00 SYLVAN
// Added validity checking for DisplayStatus to pass correct port names
//
// Rev 1.9 08 Nov 1993 17:38:16 SYLVAN
// added comments, made PollReduction really work this time :)
//
// Rev 1.8 03 Nov 1993 17:25:54 SYLVAN
// Changed parameter to Yield...
//
// Rev 1.7 02 Nov 1993 16:46:46 SYLVAN
// Added YieldToStatus Window
//
// Rev 1.6 17 Sep 1993 11:22:58 SYLVAN
// Port not paused after EOJ
//
// Rev 1.5 15 Sep 1993 11:46:32 SYLVAN
// Added MonQP_Init for .ini entry for WritePollRate interval
// Use GetBiDiTicks instead of Windows function
//
// Rev 1.4 14 Sep 1993 10:52:32 SYLVAN
// Added algorithm choices for poll reduction
//
// Rev 1.3 31 Aug 1993 15:09:28 SYLVAN
// several, see history section
//
// Rev 1.2 16 Aug 1993 11:50:48 SYLVAN
// fix keywords in header (case sensitive)
//
// Who When What
// --- --------- ----
// sdb Jul 22 93 Module created by extraction from smon.cpp
// sdb Jul 29 93 Changed to use WritePort call
// sdb Aug 4 93 Added PJL output to Begin/End job, qualified it
// sdb Aug 5 93 Null terminate stored job name
// sdb Aug 20 93 Added check for job in ValidHandle
// sdb Aug 30 93 Added hack to prevent polling for ustatus in Write
// sdb Sep 7 93 Added alternate poll reduction algorithm
// Fixed multiple printer interaction bug in Aug 30 hack
// sdb Sep 15 93 Changed alternate poll algo not to use Win GetTicks...
// sdb Sep 17 93 Not paused after EOJ
