-
- This is from memory, since I don't have the references here, and
- it has been a While.... AuxInPtr and AuxOutPtr are Pointers
- containing the addresses of the respective AuxIn Function and
- AuxOut Procedure, which are used (and not available as a standard
- Function/Procedure) by the standard TP3 I/O drivers.
-
- Each of the I/O possibilities has a corresponding Procedure/Function,
- address Pointer, and BIOS entry point as follows:
-
- Device proc/funct address BIOS entry
-
- CON:,TRM:,KBD: ConIn:Char; ConInPtr CONIN
- CON:,TRM:,KBD: ConOut(Ch:Char); ConOutPtr CONOUT
- LST: LstOut(Ch:Char); LstOutPtr LIST
- AUX: AuxIn:Char; AuxInPtr READER
- AUX: AuxOut(ch:Char); AuxOutPtr PUNCH
- USR: UsrIn:Char; UsrInPtr CONIN ?
- USR: UsrOut(ch,Char); UsrOutPtr CONOUT ?
-
- I'm not sure about the last two entry points. Also, if memory
- serves correctly, there is another Function, ConSt:Boolean, which
- is used by the KeyPressed Function, having a corresponding address
- Pointer, ConStPtr, With BIOS entry Const. if you Write your own I/O
- drivers, you should assign the address of the corresponding driver
- Function or Procedure to the proper Pointer Variable. Your question
- is a bit vague; what specific problems have you encountered? I
- think that my recollection is accurate; however, my old references
- are in an attic in Pennsylvania, While I am here in Huntsville,
- Alabama. Perhaps someone else could confirm and/or amplify on
- these observations.
