sounds really cool!

the question is - can i install ISDN software on 1.5.4 system ?

i heard it's named isdn4bsd and can be downloaded.

if so - all i need is to choose and buy hardware.

are some recommended for NetBSD?

i need cheap hardware that doesn't do much else (i have leased line modem
for internet connectivity).

does 2-port card exist?

if not - this will wait until i'll buy new machine. this hasn't enough PCI
slots
