Can someone who has successfully attached a modem or terminal please let
me know how it's done?  I have a serial cable and an 8-port serial adapter
in my model 530 -- the cable running every line straight through.

For modem communications, we need to use tip.  Here is how I've tried to
set it up:
     1. Cable from port 5 to the terminal or modem
     2. smit tty, add a tty, 8-port Asych adapter EIA-232, port 5
        enable logins, 9600 baud, no parity, 8 bit characters, XON-XOFF yes,
        terminal type DUMB, stty on run time [hupcl,cread,brkint,icrnl,opost,
        tab3,onclr,isig,icanon,echo,echoe,echok,echoctl,echoke,imabel,iexten],
        and stty attributes on login [cread,echoe,cs8,ixon,ixoff,clocal]
    3.  Step 3 has created tty4.
    4.  In smit, configure a tty
    5.  chmod 666 /dev/tty4
    6.  echo hello > /dev/tty4 doesn't echo anything to a wyse-75 I
        attach to the port, whether I use the
        straight through cable or with pins 2 and 3 switched.
    7.  tip returns the message "link down" when trying to use the port.
    8.  kermit -l /dev/tty4 -b 9600 just hangs.

Can anyone provide any insight? Has anyone successfully attached a modem who
will tell me exactly with their smit settings where and how they set it up
to use tip?  Of course I feel as if I've tried everything at this point :-).

Thanks in advance.
