COM port problem on Dell Latitude CPxJ
Posted by Ed on August 20th, 2005


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
