Thanks for the information, Wes. Unfortunately when I use IRQ5 on the "second" (SIO2) port it ceases to work on my "other" operating system (WinNT 4.0), where shared IRQs *are* possible. So guess I'm back to square one, not having any extra IRQs in my system. I'll have to choose between the two modems for Freebsd I guess.
