[comp.sys.m6809] NEED mc6850 ACIA driver for OS9 L2

houser@mcnc.org (Kevin D. Houser ) (04/05/89)

  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.
