Wow !! Now the 32 ports are detected and devices created.
# digictl -d 1 -r /dev/digi0.ctl
digi0: Got init reset after 0 us
digi0: BIOS uploaded
digi0: BIOS started after 0 us
digi0: BIOS booted after 1619 iterations
digi0: Loading FEP/OS
digi0: FEP/OS loaded
digi0: FEP/OS started after 28 iterations
digi0: Digiboard PCI PC/Xem ASIC, 32 ports found
# ls /dev/cuaD?? | wc -l
32
I will connect some modems to that ports to test and let you know.
Thank you for your time.
