Q-Device! is a tool for querying and controlling devices attached to SCSI or IDE buses for the Amiga. SCSI and IDE devices contain pages of information which describes the device's features, modes of operation and diagnostic status. In many cases these pages are configurable to allow the user or the manufacturer to tweak the device's operation. Q-Device! is capable of decoding much of this information and presenting it to the user. Experimental support was written for a pseudo-device driver which allowed Q-Device to directly query SCSI/IDE devices of other machines on the network. It requires the qdd daemon which I wrote in C, to be running on the remote machine. Support was written for both Linux and Solaris and although it worked, it never really went beyond the experimental stage. It's primary use was to allow me to test q-device against many more devices without having to physically connect and disconnect them from the Amiga.
