Sorry to OS9 newsgroup readers if this is the wrong place to ask.. is there a comp.os.os9000 ?, does comp.os.os9 also discuss os9000 ? ------------------------------------- A friend of mine who is new to OS9000 wants to write a device driver for a programmable I/O controler which does not raise an interrupt on the host PC. He says that OS9000 doesn't directly support device drivers that poll devices. He's come up with some sort of solution which he is not entirely happy with. Sorry I can't give any more details than this, Any comments ? While i'm talking OS9000, can anyone recomend a good book on writing device drivers.
