POSIX::Termios
new
Create a new Termios object. This object will be destroyed automatically when it is no longer needed. A Termios object corresponds to the termios C struct. new() mallocs a new one, getattr() fills it from a file descriptor, and setattr() sets a file descriptor's parameters to match Termios' contents.

        $termios = POSIX::Termios->new;
getattr
Get terminal control attributes.

Obtain the attributes for stdin.

        $termios->getattr( 0 ) # Recommended for clarity.
        $termios->getattr()
Obtain the attributes for stdout.

        $termios->getattr( 1 )
Returns undef on failure.

getcc
Retrieve a value from the c_cc field of a termios object. The c_cc field is an array so an index must be specified.

        $c_cc[1] = $termios->getcc(1);
getcflag
Retrieve the c_cflag field of a termios object.

        $c_cflag = $termios->getcflag;
getiflag
Retrieve the c_iflag field of a termios object.

        $c_iflag = $termios->getiflag;
getispeed
Retrieve the input baud rate.

        $ispeed = $termios->getispeed;
getlflag
Retrieve the c_lflag field of a termios object.

        $c_lflag = $termios->getlflag;
getoflag
Retrieve the c_oflag field of a termios object.

        $c_oflag = $termios->getoflag;
getospeed
Retrieve the output baud rate.

        $ospeed = $termios->getospeed;
setattr
Set terminal control attributes.

Set attributes immediately for stdout.

        $termios->setattr( 1, &POSIX::TCSANOW );
Returns undef on failure.

setcc
Set a value in the c_cc field of a termios object. The c_cc field is an array so an index must be specified.

        $termios->setcc( &POSIX::VEOF, 1 );
setcflag
Set the c_cflag field of a termios object.

        $termios->setcflag( $c_cflag | &POSIX::CLOCAL );
setiflag
Set the c_iflag field of a termios object.

        $termios->setiflag( $c_iflag | &POSIX::BRKINT );
setispeed
Set the input baud rate.

        $termios->setispeed( &POSIX::B9600 );
Returns undef on failure.

setlflag
Set the c_lflag field of a termios object.

        $termios->setlflag( $c_lflag | &POSIX::ECHO );
setoflag
Set the c_oflag field of a termios object.

        $termios->setoflag( $c_oflag | &POSIX::OPOST );
setospeed
Set the output baud rate.

        $termios->setospeed( &POSIX::B9600 );
Returns undef on failure.

有用吗？

《Linux 程序设计入门》 第四版 §5 终端 §5.4 termios结构
§5.4  termios结构

Termios是POSIX规定的标准接口，它和System V的接口termio.类似。使用数据结构termios，在termios.h中定义，该文件还包含小量的函数调用。

使用termios.h中的函数调用时，要链接合适的函数库。根据系统，可能是标准的c库或者curses库。如有必要，编译的时候需要添加：-lcurses。老系统中甚至为-lncurses。

我在创建tty后调用bash测试，发现more命令输出1屏就自动退出了，man命令有概率会发生输入控制字符的提示位置到了屏幕当中，不知道怎么设置好。。。。。。

虽然more输出1屏就退出的问题没有解决，不过还是谢谢帮助
