Hi fellows,

Can someone tell me why this PCI based modem is not recognized by the
serial driver or, what does error code -28 mean?
It's a "3Com Corp, Modem Division 56K FaxModem Model 5610c" internal
board, flashed to their latest firmware. It was recognized a short while
ago by another FreeBSD system...

Thanks, Enoch.
