Function Documentation

void serial_close (  serdev *  device  )

destrucor, has to be called after the seraial port has been used Parameters: device  the serial device obect represening the serial port Returns: void This function is the destrucor, it has to be called after the serial port has been used

int serial_configure (  int  device, int  stty_baud, char *  devname )

FIXME. Parameters: description  string describing what went wrong Returns: void This function is called whenever something went wrong in auto.c. This function stops any automated procedures.

serdev* serial_open (  char *  dev, int  stty_baud, int *  err )

initializer, has t be called before the serial port can be used Parameters: dev  the unix filename of the serial ort to be used stty_baud  the baud rate to be used err  and integer in which an errorcode will be written Returns: a pointer to an object represening the serial port This function is the initilaizer of the serial port object

int serial_read (  serdev *  device, void(*)(const char *)  inputproc )

tryes to read somethng from the serial port Parameters: serdev  the serial port object representing the serial port înputproc  a function to be called if smething was read, the string read will be passed t this funtion as a parameter Returns: int errorcode This function tryes to read somethng from the serial port. It is usally called within a thread context in a polling manner.

int serial_reopen (  serdev *  device  )

reopens and reconigures the unix deice file representing the serial port Parameters: device  the serial device obect represening the serial port Returns: void This function reopens and reconigures the unix deice file representing the serial port. It uses the confuration information store in device
