Thanks, toma, for trying this out. You are doing great. Sorry that I forgot about this snag. With both your interactive shell and the Perl debugger trying to read from your tty, the reads will interleave and not match up well with the prompts.

So your shell wrote out a prompt and then requested a read. Next, the debugger wrote out a prompt and then requested a read. The shell's request for a read was still active and so the next line you type goes to the shell even though what you see is a debugger prompt. The debugger is still waiting for its read to complete so the CGI goes nowhere.

The simplest solution is to just tell your interactive shell to stop reading from your tty for a while. I'd usually do something like "sleep 6000". Then I could interact with the debugger fine. When done debugging that session, an interupt (usually CTRL-C) would give me back my interactive shell prompt.

A second telnet session can also be useful so you aren't tempted to try to get your interactive shell prompt back while still debugging. (:

Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
