A friend of mine is running OS9/68k (Dr.Keil's implementation based on TLM Systems original port) on a Atari-ST Mega2. Now he's looking for a driver that can operate the midi port like a common RS-232 serial port. I'm aware that such a driver exists for the Cumana-OS9 implementation but it is said not to work with Keil-OS9. We are not afraid of writing such a driver ourselves under normal circum- stances, that is, if the OS9 was implemented regularily. But the Keil implementation seems to be a big hack as it has to co-exist with several oddities (from the OS9 programmer's point of view) of TOS because it uses TOS routines for screen I/O etc. In particular, the interrupt handling seems to differ from the standard OS9 way to do it. All attempts to install an interrupt service routine via F$IRQ have failed totally. Any help or pointers to a MIDI-Driver working with Keil-OS9 (V2.2) or - even better - sources for such a driver would be greatly appreciated. ========================== +---------------------------+ ***************** Lukas Zeller |\ E-Mail: /| * Never trust a * ETH Zurich, Switzerland | \_______________________/ | * computer * (SFIT, Swiss Federal | / zeller@ethz.UUCP \ | * bigger than * Institute of Technology) | / ..cernvax!ethz!zeller \ | * you can lift * ========================== +---------------------------+ *****************
