We are databasing the setup for an aircraft simulator. A PC is used with Hyperterminal over a serial interface as a standard VT100 terminal for general interface with the simulator. When the host computer requests the setup, a manual button is pressed in Access which currently creates a file with data in the right format. This file or the data which was entered into the file needs to be output on the serial port when the button is pressed and the host computer is in a "read" mode. Any suggestions? I found a reference on the web somewhere that suggested using "shell" to send the file and had an example, but could not find it again.
