I just purchased and installed a new MSI 880G-E45 motherboard. The board has a 10 pin header (# 10 missing). The manual calls it: Serial Port connector: JCOM1. I have not been able to find a part to bring this Serial Port out to the rear of the pc. Some older pc's used a semular arrangement but the pin connections between the DB9 and the motherboard connector do not match. The pin numbers should be the same on both ends. I could make one if I could find the motherboard connector with about 12 inches or more cable attached. I use serail ports with my Ham Radio Equipment.
