reading and writing to a serial device (modem)

I have a GPRS modem connected to a laptop running RH9. It's on ttyS1. I've tried it using minicom and it works.

How do I directly write to / read from it?

I've tried
echo "AT" > /dev/ttyS1
and at the same time
tail -f /dev/ttyS1
but not much happens.
