okay i try to explain better...

i want to write a program that uses the gps and so i need to read and
write directly from the serial port.
on the idl web-site there is a zip file (under user-contributed site,
section dll and dlm files) that seems to provide what i need.

if you unzip the file you get 4 files:
serial.dll and serial.dlm (to be put in a specified folder)
a readme file that is a bit like the help page that describes 4
functions
and a c-language source code (it doesn't have a main).

my goal is to be able to use the functions described in the text file:
these functions are
comm_open
comm_read
comm_write
comm_close.

all this stuff is achieved through dynamically linked modules, and in
this case it means that my idl program must be coupled with some piece
of C-language..

what i did is just putting the dll and dlm files in the right folder,
and than trying to use the functions as normal idl functions.
but they are not recognized as functions.
moreover i didn't use the c source file in any way... but i think i
should use it.. if it contained a main i could try to spawn it from
the main idl module but i can't get an executable out of it becuse it
contains no main...

thanks in advance
