Hi,
I got my 4 port serial card and installed it in my firewall today

I'm using a null modem cable to connect another server to the serial
card's pigtail but when I try to connect to the remote server with tip
or cu, all I get is "Connected". At that point I can ~^D and ~^v and
that's about it.
Connected doesn't necessarily mean there is a well-formed connection
between the two devices. Connected just means you are electrically
connected and something is on the other end of the cable. However, the
communication link may not be "synchronized." Have you tried variations
of line speed, stop and data bits, and parity? If you can connect via
the built-in serial connections of the computer, it doesn't seem like
this would be the problem.
I have a Dell PowerConnect switch that does what you're describing. If I
hit enter 2 times, it will "sync" and give me back a login.

These commands you are using are taking place on your local side only.
Is there a way I can see on the remote system if indeed I'm connecting?
If you can login into the server via ssh or console, look for processes
that would have been instantiated in order to make the connection, such
as a getty or a shell process.
If I connect one server directly to the one external serial port on
the firewall with a null modem cable I can connect with cu no problem,
and I have full control.
There are at least a couple of null wiring layouts. Your serial card may
have a different layout than your built-in serial connections. For
example, some of the handshake lines may be crossed-over. I have never
used a serial card before, but maybe you need a straight-through cable
instead of a null modem cable. If you're handy with a soldering iron and
can get your hands on some DB-9 connectors, you can make your own cables
using CAT5. Just some ideas.
I'd appreciate any suggestions.
Thanks!
