Connect GPIO pins 8-10 which will cause an external loopback. 84. doup The baud rate can be calculated by retreiving the "divisor" This is done by first setting the "divisor" flag by sending 0x80 to port base address+3 The "divisor" is then then retrieved by reading a 16-bit value from port base address which can determine the baud rate based on the frequency of the crystal on the UART chip. From the If your serial port is virtual created by some driver through USB connection, use this example to get details about these serial ports. ErrorReceived and Serial. If you choose to implement handshaking with your RS232 tester, you should know that Serial Port Tester supports DTR / CTS handshaking.
