APPENDIX TWELVE 58511 E48F GPDVV Generic parallel device handler general-purpose vector. You can use this to talk to any expansion port device; move this ad- dress into HATABS (794-831; $31A-$33F) along with an appro- priate device name such as V: or T:. See the appendix on the expansion bus. There are seven vectors in this table, corresponding to the vector tables at 58348 ($E400). 58528-58560 E4A0-E4C0 .... Blank area (all zeros). 58561 E4C1 ICIO Initialize CIO. 58588 E4DC IIN IOCB not OPEN error routine. 58591 E4DF CIO The CIO area includes the following routines: Address Routine 58640/E510 Nonexistent device error 58645/E515 Load peripheral handler for OPEN 58650/E51A Perform CIO command 58687/E53F Execute OPEN command 58716/E55C Initialize IOCB for OPEN 58742/E576 Poll peripheral for OPEN 58748/E57C Execute CLOSE command 58775/E597 Execute STATUS and SPECIAL commands 58802/E5B2 Execute GET command 58910/E610 Execute PUT command 58992/E670 Set status 58994/E672 Complete CIO operation 59029/E695 Compute handler entry point 59067/E6BB Decrement buffer length 59080/E6C8 Decrement buffer pointer 59089/E6D1 Increment buffer pointer 59096/E6D8 Set final buffer length 59114/E6EA Execute handler command 59124/E6F4 Invoke device handler 59135/E6FF Search handler table 59158/E716 Find device handler 59193 E739 PHR Peripheral handler loader.
