Thanks very much it looks like it will suit my requirements will have
a read of the spec.

Just to answer some ppl confused by the requirement for 3 RS232 - it
will be used to switch between three types of modems in a small
submarine ( one acoustic and two radio frequency)!
How exciting is that!

Rabbit?  Nice modules and you can even get a C compiler from a third 
party. 

They include something they call a C compiler but it has a number of 
incompatibilities with standard C.  For small projects you might be able 
to use it though.

Do you have to work with all three modems at the same time? Why can't you
just multiplex them to one port?

P.S. Still you have to get a PC :)

Hi rate, if it's just switching between modems this is the product we 
use in aviation (scroll down to the CE0063 Minimux)
http://www.cescom.com.au/new/products/products.html
It has 4 ports plus these units can be daisy chained to expand them.
