TERM(1) General Commands Manual TERM(1)
NAME
term - turn PC into a dumb terminal [IBM]
SYNOPSIS
term [baudrate] [parity] [bits_per_character] [-dial_string] [device]
EXAMPLES
term 2400 # Talk to modem at 2400 baud
term 1200 7 even # 1200 baud, 7 bits/char, even parity
term 8 9600 /dev/tty01
# 9600 baud, 8 bits/char, no parity, use tty01
term -atdt12345 /dev/tty01
# Start with a command to dial out
DESCRIPTION
Term allows MINIX 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 stdin (usually the console's keyboard), to the terminal or modem (/dev/tty00). The
child sits in a loop copying from the terminal or modem (/dev/tty00) 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 a minus ('-') is
sent out to the modem, usually to dial out. Term 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 term to do this, or your modem line will be reset! Term keeps the modem line open on file descriptor 9 while
running the subshell, so you can type
<&9 >&9
at the end of your ZMODEM command to connect it to the modem.
Important note: to use term, it is essential that /etc/ttytab is configured so that there is no shell hanging on /dev/tty01. If there is,
both the shell and term will try to read from /dev/tty01, and nothing will work.
