Structure BOX_CNTRL
The BOX_CNTRL structure (20 bytes) is used to store the port
configuration (baud rate, data bits, parity, stop bits,
handshaking, timing values, etc.). Here you can influence the
parameters and how they are saved.

{
char baud :5; //Baud rate for channel
// 11 = 230400 6 = 2400

// 2 = 19200 16 = 110
// 3 = 9600 12 = 75
// 5 = 4800 13 = 50
// Baudrates are coded within the first 5 bits
