First, congratulations on using Perl as it was meant to be used: in embedded systems, not in an unpleasant CGI script <g>

Second, it's not clear to me what you mean about your difficulty using select:

I thought of using a timeout on the can_read(timeout) call but the STDIN (actually redirected through TCPSERVER from the operator interface device) will reset that value when it wants more action.

You should be able to use select on both your TCP connection and STDIN; when you come out of select, zero or more file handles will be ready to read (or write, or will have exceptions on them, depending on what you were looking for). If zero, you had a timeout.

You may want to look into the Event or POE CPAN modules, both of which allow for simple creation of event-driven systems that can use select as well as timer events.
