Macros

#define RX_BUFFER_SIZE   32
 If you define this, a '\r' (CR) will be put in front of a '\n' (LF) when sending a byte. More...
 
#define TX_BUFFER_SIZE   16
 TX Buffer Size in Bytes (Power of 2) More...
 
#define FLOWCONTROL
 Defining this enables incoming XON XOFF (sends XOFF if rx buff is full) More...
 
#define FLOWMARK   5
 Space remaining to trigger xoff/xon. More...
 
#define XON   0x11
 XON Value. More...
 
#define XOFF   0x13
 XOFF Value. More...
