cfsetispeed(3) Library Functions Manual cfsetispeed(3)NAME
cfsetispeed - Sets input baud rate for a terminal
LIBRARY
Standard C Library (libc.so, libc.a)
SYNOPSIS
#include <termios.h>
int cfsetispeed( struct termios *termios_p; speed_t speed);
STANDARDS
Interfaces documented on this reference page conform to industry standards as follows:
cfsetispeed(): POSIX.1, XPG4, XPG4-UNIX
Refer to the standards(5) reference page for more information about industry standards and associated tags.
PARAMETERS
Points to a termios structure containing the input baud rate. Specifies the new input baud rate.
DESCRIPTION
The cfsetispeed() function sets the input baud rate stored in the structure pointed to by the termios_p parameter to the value specified by
the speed parameter.
If the input baud rate is set to 0 (zero), the input baud rate will be specified by the value of the output baud rate.
There is no effect on the baud rates set in the hardware until a subsequent successful call is made to the tcsetattr() function on the same
termios structure.
RETURN VALUES
Upon successful completion, the cfsetispeed() function returns a value of 0 (zero). Otherwise, a value of -1 is returned.

cfgetispeed - Gets the input baud rate for a terminal
LIBRARY
Standard C Library (libc.so, libc.a)
SYNOPSIS
#include <termios.h>
speed_t cfgetispeed(
const struct termios *termios_p);
STANDARDS
Interfaces documented on this reference page conform to industry standards as follows:
cfgetispeed(): XPG4, XPG4-UNIX
Refer to the standards(5) reference page for more information about industry standards and associated tags.
PARAMETERS
Points to a termios structure containing the input baud rate.
DESCRIPTION
The cfgetispeed() function extracts the input baud rate from the termios structure to which the termios_p parameter points.
This function returns exactly the value in the termios structure, without interpretation.
RETURN VALUES
Upon successful completion, the cfgetispeed() function returns a value of type speed_t representing the input baud rate.

Hello,
I am encountering problems when I use termios structure to set my
baud rate of serial port. Pls give me a way by which I can set
the same using a different command (1 Reply)
I have a USB serial adapter that supports arbitrary baud rates. To set a nonstandard rate in code, I'd been using the TIOCGSERIAL like so:
struct serial_struct ser_info;
ioctl(ser_dev, TIOCGSERIAL, &ser_info);
ser_info.flags = ASYNC_SPD_CUST | ASYNC_LOW_LATENCY;
ser_info.custom_divisor... (1 Reply)
Hi guys
I'm trying to connect to CISCO router using termios. So I decided to have two threads one for reading data and the other one for writing data.
And here's my code :
int mainfd=0;
char ch = {NULL};
void *write(void *)
{
char temp;
while(1)
{
temp =... (3 Replies)
