PIX 501 firewall does not accept keyboard input over serial connection.

[mkvorosten]

Hello,

I am trying to connect to a PIX 501 firewall via serial connection. My problem is that I cannot issue commands to the firewall. Whenever I try to type something into the terminal, nothing happens. I have the connection settings configured properly (9600 baud, 8 data bits, 1 stop bit, no parity, no flow control) and have tried PuTTY and HyperTerminal and have the same results. I get output from the firewall, but my keystrokes do not seem to be going to it.

Thank you.

Turns out we had a bad cable. Using a different one worked perfectly.

Thanks for letting us know.

Reminds me of some good maxims / rules of thumb / questions to remind oneself of and always ask:

1. 80% of issues are physical layer (YMMV). 80% of the ones remaining are human error.

2. Has it ever worked? If so, what's changed since then?

3. Can you recreate problem with a different device?
