|

* Name: cfsetspeed
|
||||
*
|
||||
* Descripton:
|
||||
* The cfsetspeed() function is a non-POSIX function that sets the baud
|
||||
* stored in the structure pointed to by termiosp to speed.
|
||||
*
|
||||
* There is no effect on the baud set in the hardware until a subsequent
|
||||
* successful call to tcsetattr() on the same termios structure.
|
||||
*
|
||||
* NOTE 1: NuttX does not control input/output baud independently. Both
|
||||
* must be the same. The POSIX standard interfaces, cfisetispeed() and
|
||||
* cfisetospeed() are defined to be cfsetspeed() in termios.h.
|
||||
*
|
||||
* NOTE 3: A consequence of NOTE 1 is that you should never attempt to
|
||||
* set the input and output baud to different values.
|
||||
*
|
||||
* Also, the following POSIX requirement cannot be supported: "If the input
|
||||
* baud rate stored in the termios structure pointed to by termios_p is 0,
|
||||
* the input baud rate given to the hardware will be the same as the output
|
||||
* baud rate stored in the termios structure."
|
||||
*
|
||||
* NOTE 2. In Nuttx, the speed_t is defined to be uint32_t and the baud
|
||||
* encodings of termios.h are the actual baud values themselves. Therefore,
|
||||
* any baud value can be provided as the speed argument here. However, if
|
||||
* you do so, your code will *NOT* be portable to other environments where
|
||||
* speed_t is smaller and where the termios.h baud values are encoded! To
|
||||
* avoid portability issues, use the baud definitions in termios.h!
|
||||
*
|
||||
* Linux, for example, would require this (also non-portable) sequence:
|
||||
*
|
||||
* cfsetispeed(termiosp, BOTHER);
|
||||
* termiosp->c_ispeed = baud;
|
||||
*
|
||||
* cfsetospeed(termiosp, BOTHER);
|
||||
* termiosp->c_ospeed = baud;
|
||||
*
|
||||
* Input Parameters:
|
||||
* termiosp - The termiosp argument is a pointer to a termios structure.
|
||||
* speed - The new input speed
|
||||
*
|
||||
* Returned Value:
|
||||
* Baud is not checked... OK is always returned (this is non-standard
|
||||
* behavior).

* Name: tcsetattr
|
||||
*
|
||||
* Descripton:
|
||||
* The tcsetattr() function sets the parameters associated with the
|
||||
* terminal referred to by the open file descriptor 'fd' from the termios
|
||||
* structure referenced by 'termiop' as follows:
|
||||
*
|
||||
* If 'options' is TCSANOW, the change will occur immediately.
|
||||
*
|
||||
* If 'options' is TCSADRAIN, the change will occur after all output
|
||||
* written to 'fd' is transmitted. This function should be used when changing
|
||||
* parameters that affect output.
|
||||
*
|
||||
* If 'options' is TCSAFLUSH, the change will occur after all
|
||||
* output written to 'fd' is transmitted, and all input so far received but
|
||||
* not read will be discarded before the change is made.
|
||||
*
|
||||
* The tcsetattr() function will return successfully if it was able to
|
||||
* perform any of the requested actions, even if some of the requested
|
||||
* actions could not be performed. It will set all the attributes that
|
||||
* implementation supports as requested and leave all the attributes not
|
||||
* supported by the implementation unchanged. If no part of the request
|
||||
* can be honoured, it will return -1 and set errno to EINVAL.
|
||||
*
|
||||
* The effect of tcsetattr() is undefined if the value of the termios
|
||||
* structure pointed to by 'termiop' was not derived from the result of
|
||||
* a call to tcgetattr() on 'fd'; an application should modify only fields
|
||||
* and flags defined by this specification between the call to tcgetattr()
|
||||
* and tcsetattr(), leaving all other fields and flags unmodified.
|
||||
*
|
||||
* Returned Value:
|
||||
*
|
||||
* Upon successful completion, 0 is returned. Otherwise, -1 is returned
|
||||
* and errno is set to indicate the error. The following errors may be
|
||||
* reported:
|
||||
*
|
||||
* - EBADF: The 'fd' argument is not a valid file descriptor.
|
||||
* - EINTR: A signal interrupted tcsetattr().
|
||||
* - EINVAL: The 'options' argument is not a supported value, or
|
||||
* an attempt was made to change an attribute represented in the
|
||||
* termios structure to an unsupported value.
|
||||
* - ENOTTY: The file associated with 'fd' is not a terminal.
