ХЕЛП! спасите от долбаного линукса!!!!! При приеме бинарных данных
по сом порту (ttyUSB0) система меняет байт 0x0D на 0х0А!!!! Символ
возврата каретки на символ перевода строки!!!!! Открываю порт так
//

Читаю так
unsigned short InkeyComPort(ComPort_t* s)
{
int bytes;
if( ioctl(s->fd, FIONREAD, &bytes) != 0 ) { return 0; }
if(bytes > 0)
{

read(s->fd, &read_buffer, 1); // Read the data
return 0x0100|(read_buffer);
}
return 0; }
//
Что делаю не так?!
