Ok, after much personal enlightenment I'm happy(?) to be asking publically for testers for a new device driver. The 'mdsio' driver provides support for multidrop serial busses, either using a standard RS-422/485 interface card, or a standard RS-232 serial port with DTR- or RTS-controlled transmit/receive. At this point, the driver is for -stable; at some stage DEVFS support will be added I'm sure. As the interface stands, it's simply a means for moving data on the bus; to run IP (for example) on the bus would require a simple wrapper to hang off a 'tun' device. If anyone believes they have an environment in which they could test/use this driver, please contact me for more details. -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] Collector of old Unix hardware.
