.SH DESCRIPTION
|
|
.PP
|
|
\fITerm\fR allows
|
|
\s-1MINIX 3\s-1
|
|
to talk to a terminal or modem over RS232
|
|
port 1. The program first sets the baudrate, parity and character length,
|
|
and then forks.
|
|
The parent sits in a loop copying from \fIstdin\fR (usually the console's
|
|
keyboard), to the terminal or modem (\fI/dev/tty00\fR).
|
|
The child sits in a loop
|
|
copying from the terminal or modem (\fI/dev/tty00\fR) to standard output.
|
|
Thus when
|
|
RS232 port 1 is connected to a modem, every keystroke typed on the keyboard
|
|
is sent to the modem, and every character arriving from the modem is displayed.
|
|
Standard input and output may be redirected, to provide a primitive file
|
|
transfer program, with no checking. Any argument that starts with
|
|
.B \-at
|
|
is sent out to the modem, usually to dial out. \fITerm\fP accepts
|
|
several commands that are formed by typing the escape character, CTRL-],
|
|
and a letter. Type CTRL-]? to see a list of commands. The subshell command
|
|
is very important, it allows you to type in a ZMODEM command to transfer
|
|
data. Do not quit \fIterm\fR to do this, or your modem line will be reset!
|
|
\fITerm\fP keeps the modem line open on file descriptor 9 while running the
|
|
subshell, so you can type
|
|
.PP
|
|
.in +.5i
|
|
<&9 >&9
|
|
.in -.5i
|
|
.PP
|
|
at the end of your ZMODEM command to connect it to the modem. With
|
|
.BI \-c kcmd
|
|
arguments you can bind shell commands to keys. The character just after
|
|
.BR \-c
|
|
is the key to use, the rest of the characters form the command to bind to the
|
|
key. This command also has the modem open on file descriptor 9.
|
|
.LP
|
|
Important note: to use \fIterm\fR, it is essential that
|
|
\fI/etc/ttytab\fR is configured so
|
|
that there is no login session started on the modem line.
|
|
If there is, both the login session and
|
|
term will try to read from the modem, and nothing will work.
