It's a library, you can just use it without modifying. It's the same one I use for nearly all my serial code(i.e. I use it quite a lot -- both serial ports and three USB serial converters on our server are occupied already).
Why not try it. It even included example code. I'll make it plainer:
You do this:

Hi,
Now I am programming to communicate with some network printer through TCP Socket program.By sending command "\033E 1\r" to printer,causes, check the port for error normally.
In my case i used following code

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.

cfgetispeed
cfspeed(3C)cfspeed(3C)NAME
cfgetospeed(), cfsetospeed(), cfgetispeed(), cfsetispeed() - tty baud rate functions
SYNOPSIS DESCRIPTION
These functions set and get the input and output speed codes in the termios structure referenced by termios_p. The termios structure con-
tains these speed codes representing input and output baud rates as well as other terminal related parameters. Setting the parameters on a
terminal file does not become effective until is successfully called.
returns the output speed code from the
termios structure referenced by termios_p.
sets the output speed code in the
termios structure referenced by termios_p to speed. The speed code for a baud rate of zero, is used to termi-
nate the connection. If is specified, the modem control lines are no longer asserted, which normally discon-
nects the line.
returns the input speed code from the
termios structure referenced by termios_p.
sets the input speed code in the
termios structure referenced by termios_p to speed.
RETURN VALUE
returns the output speed code from the termios structure referenced by termios_p.
returns the input speed code from the termios structure referenced by termios_p.
and return zero upon successful completion. Otherwise, they return -1 and set to indicate the error.
ERRORS
and fail when the following condition is encountered:
[EINVAL] The value of speed is outside the range of possible speed codes as specified in
WARNINGS
and can be used to set speed codes in the termios structure that are not supported by the terminal hardware.
