If you can not find the desired serial pinout here, search online, such as OpenWRT TOH or LEDE (if supported) and WikiDevi. Note, for WikiDevi, 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.

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.
