// Trantor T128 Definitions File

|
|
// This file contains definitions specific to the logic used on the T128
|
|
// parallel to scsi adapter.
|
|
//
|
|
// Revisions:
|
|
// 02-25-92 KJB First.
|
|
// 03-19-93 JAP Implemented condition build FAR and NEAR pointers
|
|
// 03-25-93 JAP Fixed up prototype typedef inconsistencies
|
|
// 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.
