Someone please help!!! I have asked about a year ago, but maybe someone can help. I need source code and or binaries for a interrupt driven (IRQ hopefully) serial device driver and descriptor that drives a motorola 6850 acia and has a 512 byte buffer. I also need to know how to change the device's absolute address just in case. I do not know how to write device drivers and don't presently have time to learn (OS9 asm formats are a real pain, ahhh but the multitasking... :->) how to write my own. However I could successfully modify one that runs under OS9 level 2. Anyone have any Ideas? Microware how about a little help.

I think that *The Complete RAINBOW Guide to OS-9* by Puckett and Dibble contains such a device driver, though I'm not sure about the buffer size. As for the device's address, that's a function of the hardware itself, and of the device descriptor rather than the driver. James
