The communication buffer for each port of the H2-SERIO is 16 bytes long. However, means are provided in the WinPLC SDK functions to write long strings of data through this size buffer. You send the long string and then the buffer will communicate back how many bytes were sent. Based on this number you can reset your pointer in your string and send again. In this manner long strings of data can be sent. Of course, at higher baud rates the number of bytes that get sent each time will be much larger.
