COM port problem on Dell Latitude CPxJ

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

I have a Dell Latitude CPxJ that I would like to use with an RS-232
interface.  However, the RTS and DTR pins are always active.  I need
them to start inactive and the software to switch them to control a
radio.  My laptop has BIOS version A16 and Windows 2000 SP4.

Thanks,  Ed
