TechInfoDepot:DD-WRT/Serial port pinouts
If you can not find the desired serial pinout here, search online, such as OpenWRT TOH or LEDE (if supported) and TechInfoDepot. Note, for TechInfoDepot, it is best to just search for your router name + wiki in your favorite search engine. Also try searching forums here and at OpenWRT/LEDE.

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.

D-Link DIR-615 D3
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.
D-Link 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.
D-Link 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。

E2000 has the same pinout. Looking from the back of the router, the serial port is the 5 holes above the 2x6 JTAG port. Again, looking from the back of the router: Vcc - Rx - Tx - ? - Gnd

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