SmartSerial is an serial terminal application that does one thing well - connecting and communicating with devices via serial port.

Here's why it's smart:

• A clean and simple user interface. The main window is DPI aware, resizeable and customisable to suit your screen and the amount of data you need to view. There are no more controls than necessary to do the job, and everything has hover-enabled help popups that describes what it does. The application will remember your customisation between program launches.
• The port list is automatically updated each time a USB serial device is attached or removed from the computer. If you're not already connected to a port, the new port will automatically be selected, taking the guesswork out of which COM port was allocated to a USB device. You can auto-connect to new devices if you like.
• Editable configuration for connection settings such as baud rate and auto-connect. Save different configurations for different devices, and double-click the configuration file to start SmartSerial with these settings.
• Track serial communication and command history which are displayed on screen and are persistent between sessions. Click a previous command to edit, or Ctrl+Click to resend immediately.
• Edit and export command lists - create a library of common commands for different projects and open or import them at will. Double-click command lists to start SmartSerial with these commands.
  
• Save serial data to text files for external use or for an archive of activity.
  
• By default commands are sent with CRLF line endings. In the command text box use Enter to send with CRLF, or use keyboard modifier Ctrl+Enter to send with LF or Shift+Enter to send without line endings. Command history saves line endings and history displays which line ending was used. Ctrl+Click on a command history item sends the saved command including the line ending used.
