Rs232

I am trying to control an external modem using an RS232 connection, and I am having a very difficult time figuring out how to go about this. I am using a gcc compiler, and would greatly appreciate any suggestions.

-Thanks

To work the modem, you need to know it's command set - the list of all the commands it will respond to. Google "modem command set" or language, and see if you can find that.

Then you'll need to also get the RS232 protocol - and again, google is your friend.

You might find both hidden away on code depots like sourceforge.net.

Good luck.
