conflicting tasks (usb and serial)

    Jul 03 2006 | 1:26 pm
    Dear list,
    I am running two USB serial converters, (which steer stepper motors) as well
    as a midi out.
    The two tasks seem to conflict when simultaneous and hence crash, although
    work fine independently. I will attempt to alternate the serial and midi
    output but this seems like a bit of a farmers solution.
    G4, OS X.3.9,
    doepfer CTM on midi,
    usb serial converters (
    2 serials on a usb bus, midi direct from laptop,
    Any ideas much appreciated
