How to check if remote db is up or down?

I would like to create a simple webpage that lists the status of all our informix db instances. The page will be located on a web server WITHOUT informix installed. Is it possible to remotely check and see if a particular instance is up/down? Perhaps using telnet to log into the server port number and see if anything is listening? Any ideas or suggestions? Is there perhaps a unix utility available that can do this task? (ie: input a host and tcp connect and it queries if up/down, etc..) Thanks.

Here are some links ... http://www-106.ibm.com/developerworks/db2/zones/informix/library/techarticle/sm_prodinfo.html http://www14.software.ibm.com/webapp/download/product.jsp?id=MBEN-4ZLHHX&s=z&cat=&S_TACT=TrialsAndBetas&S_CMP= However it is easier to do a google search on "Informix Server Administrator (ISA)" and select the top link.
