Short: Parallelport testing Hard- and Software Author: Ber, T-Online:03043618030001 Uploader: Berno (Ber), Berlin/Germany Type: driver/other Architecture: m68k-amigaos This archive contents a description to built a parallelport test adaptor and two programmes to control the bits at this port. (Only amiga internal parallelport.) The hardware checks the lines and indicates a dataflow over the port. (All parallelports e.g. of I/O-cards or other [non-amiga] pc's.) With one programme you are able to set and clear all databits and the signals Bsy, POut and Sel additional (testing the port). The other programme is only to set and clear the databits. This is usefull to control a connected relay-card. In both programmes you can switch the power-led high and low (this switches also the audio filter in most amiga models).
