// 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.
