Before you can write or read data, both the serial port object and the device must have identical communication settings. Configuring serial port communications involves specifying values for properties that control the baud rate and the serial data format. The following table describes these properties.
Specify the rate at which bits are transmitted
Specify the number of data bits to transmit
Specify the type of parity checking
Specify the number of bits used to indicate the end of a byte
Specify the terminator character
Refer to the device documentation for an explanation of its supported communication settings.
