modem connection

[Jenny]

I am new to Java and would like to know the following.

My server needs to wait for any incoming call (from a client computer) through
the modem.

1) What library function should I use in order to detect any incoming call
from the modem?

2) After the connection is made, how can I communicate to the client. Say,
the client will send me a string and my server will search on the local database
based on the incoming string. Then return a text file, which contains the
result, back to the client's computer.

Any sample site I can get information on this issue?

Thanks.
