I am not sure what you mean by "unavailable": every device in AIX is basically in one of two states (if present at all): do a lsdev -C and you should see a list of devices some of which are in state "Defined" and some are in "Available".

"Defined" menas the definition is there but the device is not usable. "Available" means the device is working. "working" in this case means not only it is (electrically) connected but also that the correct drivers are installed and running. If in doubt, post the output of the commands:

Code:
lscfg -vp
lsdev -C

I hope this helps.

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. SEE ALSO
