Hello All,
I have been through Chapter 14 Section 3 on Dial-in Service.
When I tested the dial-in connection, I see random characters
echoed to the terminal window. Do I have a problem with
terminal type or is there a problem with my setup? I am using
a cirrus-logic 3450 chipset modem and FreeBSD 3.2.
Here are the important files.
/etc/ttys

# name getty type status comments
#
# This file specifies various information about terminals on the system.
# It is used by several different programs. Common entries for the
# various columns includes:
#
# name The name of the terminal device.
#
# getty The program to start running on the terminal. Typically a
# getty program, as the name implies. Other common entries
# include none, when no getty is needed, and xdm to start the
# X Window System.
#
# type The initial terminal type for this port. For hardwired
# terminal lines, this will contain the type of terminal used.
# For virtual consoles, the correct type is cons25. Other
# common values include network for network connections on
# pseudo-terminals, dialup for incoming modem ports, and unknown
# when the terminal type cannot be predetermined.
#
# status Must be on or off. If on, init will run the getty program on
# the specified port. If the word "secure" appears, this tty
# allows root login.
#
# This entry needed for asking password when init goes to single-user mode
# If you want to be asked for password, change "secure" to "insecure" here
console none unknown off secure

#
# Most of the table entries here are just copies of the old getty table,
# it is by no means certain, or even likely, that any of them are optimal
# for any purpose whatever. Nor is it likely that more than a couple are
# even correct.
#
# The default gettytab entry, used to set defaults for all other
# entries, and in cases where getty is called with no table name.
#
# cb, ce and ck are desirable on most crt's. The non-crt entries need to
# be changed to turn them off (:cb@:ce@:ck@:).
#
# lc should always be on; it's a remainder of some stone age when there
# have been terminals around not being able of handling lower-case
# characters. Those terminals aren't supported any longer, but getty is
# `smart' about them by default.
#
# Parity defaults to even, but the Pc entry and all the `std' entries
# specify no parity. The different parities are:
# (none): same as even except -inpck instead of inpck for login.
# ep: getty will use raw mode (cs8 -parenb) (unless rw is set) and
# fake parity. login will use even parity (cs7 parenb -parodd).
# op: same as ep except odd parity (cs7 parenb parodd) for login.
# op overrides ep.
# ap: same as ep except -inpck instead of inpck for login.
# ap overrides op and ep.
# np: 1. don't fake parity in getty. The fake parity garbles
# characters on non-terminals (like pccons) that don't
# support parity. It would probably better for getty not to
# try to fake parity. It could just use cbreak mode so as
# not to force cs8 and let the hardware handle the parity.
# login has to be rely on the hardware anyway.
# 2. set PASS8, giving cs8 -parenb -istrip -inpck.
# np:ep: same as np except inpck.
# np:op: same as np:ep except for parodd (but parodd is overridden).
# np:ap: same as np except istrip.
