            better double check this!
            with SCO Xenix and a Compaq your
            console screens are tty01 through tty10-12
            You switch from screen to screen by holding down the
            Alt key and pressing the Function key corresponding to
            the tty number you want.

     Your COM1 port is tty1a (if for a modem use tty1A)
     Your COM2 port is tty2a (if for a modem use tty2A)

     You need to figure out what port your modem is really on first.
     Then put the correct entry in the Devices file.  If you have a
     valid entry in your Devices file, you dont have to specify the
     line to the cu program.  If what your trying to do with above
     cu command is direct connect to the modem to set the registers,
     it should look more like this:

                   cu -s2400 -lttyXX dir

     You should set up your 2400 at 2400.  

Hope this helps.
