- i just rebooted my system with a couple of changes to it and now have gotten
- my com3 port to work, set to IRT2.
-
- Thanks to everyone that replied telling me how AT machines redirect IRQ2 to
- IRQ9 in hardware.
-
- My COM3 is set on the hardware card as IRQ2. Using the COMM2211 beta drivers
- from IBM (I think) I set it up like this:
- device=c:\os2\comm.sys (3,3e8,9,i) (4,2e8,5,i)
- or something like that.
-
- Now when it boots up it doesn't report any problems with any of the com
- ports, and I can go to the OS/2 command line and use MODE to see and
- change COM1, COM3, COM4. (COM2 is used by the mouse).
-
- Now all I have to do is figure out a way to move the mouse to COM4. :)
-
- I have one more question though. It was explained to me a while back that
- IRQ3 would be answered first if IRQ3 and IRQ4 both had data coming in, and
- to solve a problem where moving the mouse would abort a download because
- the mouse was on IRQ3, and the mode on IRQ4.
-
- Now, if my COM3 is on IRQ2, redirected as IRQ9, then will its interupt
- be taken first because IRQ2 comes before IRQ3, or will it be treated as IRQ9,
- coming after IRQ5 in the order of hierchy.
-
- Thanks
- Greg
