How am I expected to enter these AT commands?

Make what is called a ``direct'' entry in your /etc/remote file (see remote(5)). For example, if your modem is hooked up to the first serial port, /dev/cuaa0, then put in the following line:

    cuaa0:dv=/dev/cuaa0:br#19200:pa=none

Use the highest bps rate your modem supports in the br capability. Then, type tip cuaa0 (see tip(1)) and you will be connected to your modem.

If there is no /dev/cuaa0 on your system, do this:

    # cd /dev
    # sh MAKEDEV cuaa0

Or use cu as root with the following command:

    # cu -lline -sspeed

with line being the serial port (e.g. /dev/cuaa0) and speed being the speed (e.g.57600). When you are done entering the AT commands hit ~. to exit.
