Hi Roger, Take a look at
Help>>>Find Examples>>>Hardware Input adn Output>>>Serial>>>Serial Communications.VI The VT100 was one of the first "dumb terminals" and was used to replace old teletypes and line printers. The example I cited will let you specifiy a string you want to send out the serial port (like typing in hypertermial). It will then look for a response and show you what it gets. That example should get you started. Post updates if things get sticky.
