If it's one of those 10-pin 0.1" pitch IDC headers with only 9 pins installed then the vast majority of them have the same pinout - which is designed to match with a 9-pin D-type connector using a straight cable. If you have access to a meter then a quick confidence check is to verify that the pin that's on it's own next to the missing one is connected to ground. Another test is to use a terminal emulation program (something like teraterm) set up with flow control disabled and no local echo and check for an echo if you jumper the serial in and out pins.
