     /dev/ttys3 and /dev/ttyS3 are not the same... case is important (S
    and s.)
     On my machine, which uses COM 2 (/dev/ttyS1):

    [root@linuxbox /root]# setserial /dev/ttys1
    /dev/ttys1: Input/output error

    [root@linuxbox /root]# setserial /dev/ttyS1
    /dev/ttyS1, UART: 16550A, Port: 0x02f8, IRQ: 3

     The Motorola SM56 seems to be a 'softmodem', not a true hardware
    modem.
     You can find the Linux drivers for RedHat 7.3, 8.0 and 9 at:
