0x11 (17) bytes being filtered of the inbound serial stream
If you have turned on software flow control or are using SERIAL_MODE_RARE, the system will filter out 0x11 bytes in the inbound serial stream because it thinks these bytes are XON flowcontrol commands. XON = ctrl-q = 0x11 = 17 XOFF = ctrl-s = 0x13 = 19 If you are sending these bytes as data, you should turn off software flow control and not use SERIAL_MODE_RARE. SerialMode defines how the data is filtered when received. Here is the definitions of the serial modes as I understand them: SERIAL_MODE_RAW Do not filter input stream (including XON and XOFF). SERIAL_MODE_RARE Same as _RAW, but obey XON/XOFF flow-control and use it on input. SERIAL_MODE_COOKED Obey software flow-control. Also strip the high bit from the input stream (i.e., 7-bit input bytes).
