Public Member Functions | |
TTYSession (const char *name, int pri=0, int stack=0) | |
Create TTY stream that will be managed by it's own thread. | |
![]() | |
void | interactive (bool flag) |
Set tty mode to buffered or "interactive". | |
bool | isPending (Pending pend, timeout_t timeout=ucommon::Timer::inf) |
Get the status of pending operations. | |
void | setTimeout (timeout_t to) |
Set the timeout control. | |
int | sync (void) |
Flushes the stream input and out buffers, writes pending output. | |
TTYStream (const char *filename, timeout_t to=0) | |
Create and open a tty serial port. | |
virtual | ~TTYStream () |
End the tty stream and cleanup. | |
![]() | |
int | getBufferSize (void) const |
Get the "buffer" size for buffered operations. | |
Error | getErrorNumber (void) const |
Often used by a "catch" to fetch the last error of a thrown serial. | |
char * | getErrorString (void) const |
Often used by a "catch" to fetch the user set error string of a thrown serial. | |
Serial & | operator= (const Serial &from) |
Serial ports may also be duplecated by the assignment operator. | |
void | sendBreak (void) |
Send the "break" signal. | |
Error | setCharBits (int bits) |
Set character size. | |
Error | setFlowControl (Flow flow) |
Set flow control. | |
Error | setParity (Parity parity) |
Set parity mode. | |
Error | setSpeed (unsigned long speed) |
Set serial port speed for both input and output. | |
Error | setStopBits (int bits) |
Set number of stop bits. | |
void | toggleDTR (timeout_t millisec) |
Set the DTR mode off momentarily. | |
virtual | ~Serial () |
The serial base class may be "thrown" as a result on an error, and the "catcher" may then choose to destory the object. | |

![]() | |
void | allocate (void) |
Used to allocate the buffer space needed for iostream operations. | |
void | endStream (void) |
Used to terminate the buffer space and clean up the tty connection. | |
int | overflow (int ch) |
This streambuf method is used to write the output buffer through the established tty port. | |
TTYStream () | |
This constructor is used to derive "ttystream", a more C++ style version of the TTYStream class. | |
int | uflow (void) |
This streambuf method is used for doing unbuffered reads through the establish tty serial port when in interactive mode. | |
int | underflow (void) |
This streambuf method is used to load the input buffer through the established tty serial port. | |
![]() | |
virtual int | aRead (char *Data, const int Length) |
Reads from serial device. | |
virtual int | aWrite (const char *Data, const int Length) |
Writes to serial device. | |
void | close (void) |
Closes the serial device. | |
void | endSerial (void) |
Used as the default destructor for ending serial I/O services. | |
void | error (char *err) |
This service is used to thow application defined serial errors where the application specific error code is a string. | |
Error | error (Error error, char *errstr=NULL) |
This service is used to throw all serial errors which usually occur during the serial constructor. | |
void | flushInput (void) |
Used to flush the input waiting queue. | |
void | flushOutput (void) |
Used to flush any pending output data. | |
void | initConfig (void) |
Used to initialize a newly opened serial file handle. | |
void | open (const char *fname) |
Opens the serial device. | |
void | restore (void) |
Restore serial device to the original settings at time of open. | |
Serial () | |
This allows later ttystream class to open and close a serial device. | |
Serial (const char *name) | |
A serial object may be constructed from a named file on the file system. | |
void | setError (bool enable) |
This method is used to turn the error handler on or off for "throwing" execptions by manipulating the thrown flag. | |
int | setLineInput (char newline=13, char nl1=0) |
Set "line buffering" read mode and specifies the newline character to be used in seperating line records. | |
int | setPacketInput (int size, uint8_t btimer=0) |
Set packet read mode and "size" of packet read buffer. | |
void | waitOutput (void) |
Used to wait until all output has been sent. | |

char * | pbuf |
