cgi - call a script interactively

[Daniel L Quigley-Skillin]

Title: Message

I'm looking for suggestions, or help producing code that will call another script and allow me to interactively enter data.  What I'm looking to do is have a web page that shows the constantly updating data and have a form with a single text input to send commands to the script.   I've looked at cgi-telnet and it has two flaws.  The first, it doesn't call the script I want to work with.  Second, it only attempts refresh after a command is entered, ie it waits for a reply to your command, rather than expecting information at any point in time.   Any help would be appreciated.   Thanks in advance,   D-
