Dear HP41 & PC enthusiasts :
For using HPILCOM from Hans Brüggemann I need the correct wiring between the 9pin COM1 interface connector of the PC and the 25pin interface connector of the HP-IL/RS232 interface Box.
Please give additional informations about the needed COM1 mode : Hardware interfacing or software interfacing ?
Waiting for your help :-) Christoph Klug
