== Article Purpose==
本文旨在提供一些对开始使用 Linux<sup>&reg;</sup> TTY工具有用的初步信息。
这些工具对于与 [[Serial TTY overview|TTY]]终端进行交互很有用。

== Introduction ==
These tools use TTY sysfs and character device directly (See [[Serial TTY_overview#APIs description|TTY user space interface]] for further details).

==Tools list==
Please find below a list of useful TTY tools provided by Linux<sup>&reg;</sup>  community:

* '''fuser''' <ref>[https://linux.die.net/man/1/fuser fuser man page]</ref> - to identify processes using files or sockets.<br/>
* '''inputattach''' <ref>[https://linux.die.net/man/1/inputattach inputattach man page]</ref> (based on termios API) - to attach a serial line to an input-layer device. <br/> Inputattach attaches a serial line to an input-layer device via a line discipline. Exactly  one  of  the available modes must be specified on the command line.
* '''kermit''' <ref>[https://linux.die.net/man/1/kermit kermit man page]</ref> -  transport and platform independent interactive and scriptable communications software. <br/> C-Kermit is a modem program, a Telnet client, an Rlogin client, an FTP client, an HTTP client, and on selected platforms, also an X.25 client. It can make its own secure internet connections using IETF-approved security methods including Kerberos IV, Kerberos V, SSL/TLS, and SRP and it can also make SSH connections through an external SSH client application. It can be the far-end file-transfer or client/server partner of a desktop Kermit client. It can also accept incoming dialed and network connections. It can even be installed as an internet service on its own standard TCP socket, 1649 [RFC2839, RFC2840].<br/>

* '''ldattach''' <ref>[https://linux.die.net/man/8/ldattach ldattach man page]</ref> (based on termios API) - to attach a line discipline to a serial line. <br/> The ldattach daemon opens the specified device file (which should refer to a serial device) and attaches the line discipline ldisc  to  it  for processing  of  the  sent  and/or received data.  It then goes into the background keeping the device open so that the  line  discipline  stays loaded. The line discipline ldisc may be specified either by name or by number. In order to detach the line discipline, kill the ldattach process. With no arguments, ldattach prints usage information.
* '''minicom''' <ref>[https://linux.die.net/man/1/minicom minicom man page]</ref> - friendly serial communication program. <br/> Minicom  is a communication program which somewhat resembles the shareware program TELIX but is free with source code  and  runs  under  most Unices. Features  include dialing directory with auto-redial, support for UUCP-style lock files on serial devices, a separate script language interpreter, capture to file, multiple users with individual configurations, and more.
* '''setserial''' <ref>[https://linux.die.net/man/8/setserial setserial man page]</ref> - To get/set Linux serial port information. <br/> Setserial is a program designed to set and/or report the configuration information associated with a serial port. This information includes the I/O port and the IRQ used by a particular serial port, and whether or not the break key should be interpreted as the Secure Attention Key, and so on.
* '''stty''' <ref>[https://linux.die.net/man/1/stty stty man page]</ref> (based on termios API) - to change and print terminal line settings.
* '''tty''' <ref>[https://linux.die.net/man/1/tty tty man page]</ref> - to print the file name of the terminal connected to standard input
{{Info|The descriptions above are provided by the manual pages of the tools.}}

==Getting started ==
Examples of TTY tools usage are handled in the following articles :
* [[How to use TTY with User Terminal|How to use TTY with User Terminal]]
* [[How to transfer a file over serial console]]

==Installation on your target==
Some of the TTY tools aren't embedded by default in [[OpenSTLinux distribution]]. They can be compiled independently and then installed on the target (see [[STM32MP1_Developer_Package#Adding_Linux_user_space_applications|Adding Linux user space applications]]).
