I need to create a piece of TCL code that monitors serial ports under
Windows NT. Ultimately,
I will be adding 16 ports to my computer and will need to monitor all of
them. Does anyone
have any sample code that creates a server that will setup,
periodically poll the serial lines
and print the data received?

For nonblocking read (polling) or event-driven I/O (fileevent) to work
with serial devices on Windoze, you'll need ExpectNT. Look at:
