Summary:
The pin assignments for the serial port B
connector are incorrectly documented in the Product
Guide for the D845BG and D845PT desktop boards.
These pin assignments differ from the pin
assignments used on the Intel D845WN and D845HV
Desktop Boards.
Details:
The correct pin assignments for the serial port B
connector on the D845BG and D845PT desktop boards
are as follows:
| Pin # | Signal | Descriptions |
| 1 | DCD | Data Carrier Detect |
| 2 | DSR | Data Set Ready |
| 3 | RX | Receive Data |
| 4 | RTS | Ready to send |
| 5 | TX | Transmit Data |
| 6 | CTS | Clear to Send |
| 7 | DRT | Data Terminal Ready |
| 8 | RI | Ring Indicator |
