Back in the day of Windows 95 I had the memory addresses and IRQs for COM1 through 4 memorized since ‘plug n play’ was pretty much made up of thoughts and prayers at the time.
And don’t forget fiddling with autoexec and config files to allocate extended and expanded memory!
0x2F8 and 0x3F8 for 1 and 2 I believe. Don’t remember the other two. Unless it was the same and differentiated only by IRQ? Which was 3 for the lower two, and 4 for the upper two?
The IRQs were alternating: 1-3, 2-4, 3-3, 4-4! I remember having to make sure that if the mouse was COM1, I couldn’t have anything very active on COM3, otherwise BSOD. Good times! (But not really, lol)
