- * Modifications:
- *  August 21, 2000 MLR Added +r option, so that the flag is just for this
- *                      module, rather than requiring it to be in Makefile.Vx
- *  Dec. 5, 2001 MLR    Fixed bug in computing following error
- *  Dec. 7, 2001 MLR    Fixed bug in converting from EPICS to MM4000 units when
- *                      building trajectory.
- *  Oct. 28, 2002 MLR   Fixed bug in reporting updated trajectory positions after 
- *                      padding. Was not a problem in executing trajectory, only in 
- *                      values reported to EPICS
- *  Dec. 18, 2003 MLR   Changed flyback (now a misnomer) so it does EPICS move to 
- *                      current motor positions, not start positions.  
- *                      Start position move did not work because motors already 
- *                      thought they were there (if no encoder error) and motor 
- *                      record did nothing.
- *  Feb. 12, 2004 MLR   Added delay after starting trajectory execution.
- *                      This is an attempt to eliminate problem where MM4000 seems 
- *                      to sometimes ignore TP command right after trajectory 
- *                      execution starts.  
- *                      Also, first MS sometimes comes back saying motors are not 
- *                      moving yet, so software thinks trajectory is done.
- *                      Converted to OSI
- *                      Converted to new version of seq which changes call to 
- *                      seq_pvPut
- *  Oct.  1, 2004 MLR   Changed from using asynRecord (previously generic serial 
- *                      record) to using asynOctetSyncIO calls.
- *                      This fixed bugs in I/O due to timing, and is simpler and 
- *                      cleaner.
- *  Feb.  6, 2005 MLR   Changes for last version of asyn; terminators done 
- *                      differently.
- *  Mar. 28, 2005 MLR   Increased number of pulses; added readback during trajectory
- *                      download to prevent buffer overflow.
- *  Apr. 29, 2005 MLR   Changed timeout to 30 seconds - necessary?
- *  Apr. 12, 2006 MLR   Changed from strtok_r to epicsStrtok_r
- *  Jan. 18, 2007 MLR   Use new include file, "trajectoryScan.h" to eliminate 
- *                      duplication with new XPS trajectory scan SNL program.
- *                      Clean up code, assign EPICS motor PVs in init().
