//  Trantor P3C Definitions File
//
//  Revisions:
//      09-01-92 KJB    First.
//      02-25-93 KJB    Reorganized, supports dataunderrun with long delay
//                          for under run on large xfers. Can we fix this?
//      03-12-93  KJB   Now supports polling thru CardInterrupt and
//                          StartCommandInterrupt/FinishCommandInterrupt.
//      03-19-93  JAP   Implemented condition build FAR and NEAR pointers
//      03-25-93  JAP   Fixed up prototype typedef inconsistencies
//      04-05-93  KJB   Fixed function prototype.
//      05-14-93  KJB   Added CardParseCommandString for card specific
//                      standard string parsing across platforms.
//                      Changed CardCheckAdapter to accept an
//                      Initialization info from command line, ie
//                      force bi-directional ports, etc.
//                      All functions that used to take an PBASE_REGISTER
//                      parameter now take PWORKSPACE.  CardCheckAdapter
//                      takes the both a PINIT and a PWORKSPACE parameters.
