i have downlaod the COMMAPI from java sites but i am little confused while
reading its documentation bcz i have found the following line which is mush
confusing for me.
"The javax.comm.properties file must be installed. If it is not, no ports will
be found by the system. "

i don't know what does it mean or how can i install this file.
and second one is that i am using jdk1.4, i just want to know is these settings
are same for jdk1.6 and jdk1.4.

for more idea see the attachement file!


and if you have it's code then please!

i am in to much trouble because
I want to read  the com port  of my computer  and i don't have idea to do it! would
you tell me in detail which class  or package  I should use to get it done.
Any quick  help in detail will be highly appricated.
thanks
please send me the settings and code in detail if possible!

you must copy the file to /jre/lib/ext

its an extension to the JRE.
