The serial port runs at 115200 baud, 8 bits, no parity, 1 stop bit using ANSI terminal emulation.

The serial port runs at 115200 baud, 8 bits, no parity, 1 stop bit using ANSI terminal emulation. Levels are not RS232 voltage levels, but +3.3V TTL logic. Use level shifter (Max232/Max3232/DS275 etc.) to correct this. Also a USB to serial phone cable will work in most cases. A cable with a Prolific 2303 works fine to access the router as a device (Eg. to get a bootloader commandline). It does not work in host mode to control USB devices. The VCC pin puts out 3.3V.

The serial port runs at 57600 baud, 8 bits. Voltage levels are +3.3V TTL logic, which means TX transmit at 3.3V and VCC is 3.3V. RX has a pull-up resistor. Port is /dev/tts1.
Dlink DIR-300 revb
NOTE: RevB is completely different hardware, based on Ralink RT3050 SoC. The serial port runs at 57600 baud, 8 bits, no parity, 1 stop bit using ANSI terminal emulation. Levels are not RS232 voltage levels, but +3.3V TTL logic. Use an interface converter chip (Max232/Max3232/DS275 etc.) to connect to standard RS-232.
Dlink DIR-300 revb (Chinese)
注意: RevB硬件结构是完全不一样的,使用的是雷凌RT3050芯片。串口使用的是57600波特率,配置为n,8,1,电平3.3V的TTL逻辑电平并非RS232的电压,所以需要通过电平转换芯片(Max232/Max3232/DS275 etc.)然后连接到RS-232上。

You have to short R356, if not, the TX will not going to work.
