◆ bytesReady()

void cyo::Transceiver::bytesReady ( QTcpSocket *  xm)

this will throw and exception if error occurs, user can act on the exception or let the system die

do this way incase of MAC coming in

there are 4 cases we need to handle:

  1. The socket did not receive enough data to be a complete message, we only received a partial
  2. There is exactly enough data in the socket buffer to read a message
  3. There is more than enough data in the socket buffer to read a message but not enough to read 2 messages
  4. There is enough data in the socket buffer to read multiple messages

Cases 2 we successfully read some data

number of bytes in the message

this is without the initial size

Cases 3 and 4 loop and try to read more data if they are available

Cases 1 just exit the function and wait for more data to come in commitTransaction() will actually rollback if it detects there was an error and return false
