Hi folks and your quite welcome.
I know in my topic that I may have contridicted myself but I wanted to give as much information as possible without "loosing" peoples train of thought.
As far as my typing skills, well, If I have my "true blue" 10 year old IBM keyboard, I type reasonably fast. Put me on a newer keyboard and my typing skill drop to sub "hunt and peck" mode.
(dont ask me why, I just love older IBM keyboards, must be the click?)
At any rate, it was well worth typing to get the responses that it was useful and appreciated. Thanks to one and all.
BTW, I said that you CANT use 2 or more devices concurrently using 1 IRQ. This is sorta true and sorta not. One of those wonderful "gray areas" we love to exploit.
I said "can`t" because in most cases, you truely cant truely "share" an IRQ. But of course, there are exceptions to almost any rule.
Next up, DMA channels......that is, when my fingers heal somewhat.
