| Issue |
We're going to write a special "Dev.ser" driver for our own serial protocol.
We need information about the structures "input_buffer", "canon_buffer", "output_buffer" and "termios".
Do you have a description for these structures?
|
| Solution |
The termios structure is defined in the /usr/include/termios.h header file:
struct termios {
tcflag_t c_iflag; /* Input Modes */
tcflag_t c_oflag; /* Ouput modes */
tcflag_t c_cflag; /* Control Modes */
tcflag_t c_lflag; /* Local Modes */
cc_t c_cc[NCCS]; /* Control Characters */
unsigned short zero[3];
unsigned short c_status; /* device status */
unsigned short c_qflag; /* QNX Specific flags */
unsigned short handle;
speed_t c_ispeed; /* Input Baud rate */
speed_t c_ospeed; /* Output baud rate */
};
The source to Dev.ser is available in the free software archive:
http://www.qnx.com/cgi-bin/dir_find.cgi?/usr/free/
That source will show how those structures are used in the original Dev.ser code which should be useful in your application.
