Hmm, I have 7 lights on my external modem (a US Robotics Sportster):
AA CD RD SD TR CS ARQ/FAX
AA = auto answer
CD = carrier detect
RD = receiving data
SD = sending data
TR = terminal ready
CS = clear to send
ARQ/FAX = error control/fax operations
When I turn on my modem (but not the computer) the CS lamp is on:
aa cd rd sd tr CS arq/fax
When I turn on the computer (and the computer serial port is connected
to the modem) the TR lamp goes on.
aa cd rd sd TR CS arq/fax
After the computer connects to the isp, the ARQ/FAX and CD lamps go
aa CD rd sd TR CS ARQ/FAX
The RD and SD lights flicker as data gets sent through the modem.
aa CD RD SD TR CS ARQ/FAX
So, do you have a Terminal Ready lamp? It should turn on when your
computer is talking to your modem (even if you haven't called out
I have found that the lamps behaved the same in the olden days, when I
used to dial out from DOS.

Hmm. Could be the permissions problem mentioned by other people.
Or your wvdial is talking to the wrong device. Here's my
Modem = /dev/ttyS0
Baud = 38400
Phone = my_isps_phone_number
Username = bjb
Password = my_dialup_password
New PPPD = yes
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 S11=55 +FCLASS=0

Ah, perhaps the info is going to stderr. It can be piped to less.
command 2>&1 | less
programs have two output streams by default, one called stdout and one
called stderr. When you pipe output, or redirect it into a file, you
are redirecting only stdout. stderr still goes to the console. If
you want to catch stderr as well, you have to say so, as above (what
the above says is "send stderr to where stdout is going").
File descriptor 0 is stdin (standard in), fd 1 is stdout, fd 2 is

Old commands get saved in a file called .history in your home account.
This is a per-user thing, if you logged in as root, your commands
will be saved in ~root/.history; if you logged in as ian,
your saved commands will be in ~ian/.history.
Oops, according to the bash man page it's $HOME/.bash_history,
if you haven't changed it to something else.
Oh look: Talking about the environment variable HISTFILE:
The name of the file in which command history is
saved (see HISTORY below). The default value is
~/.bash_history. If unset, the command history is
not saved when an interactive shell exits.

Oh dear. More sympathies. (Wow, 15 years of data.)
