See protocol definition here http://www.can232.com/docs/can232_v3.pdf and here http://www.can232.com/docs/canusb_manual.pdf
Commands not supported/not implemented: s, W, M, m, U

Commands modified:
S - supports not declared 83.3 rate, refer to https://github.com/latonita/CAN_BUS_Shield fork
F - returns MCP2515 error flags
Z - extra Z2 option enables 4 byte timestamp vs standard 2 byte (60000ms max)
