Anyway, my 486 has a 16450 UART serial card. My understanding is that there are many limitations to this kind of card and I am wondering what my options are in terms of upgrades that work with FreeBSD. The ISDN adapter I'm using is a 3Com ImpactIQ and it says that with compression it can get speeds up to 230kbps. I'm getting about 85kbps with it now. The 3Com ImpactIQ came with advetisements for serial cards with 16750 UARTS on them. Do these work with FreeBSD? Does anyone have any opinions on them?
