Serial-port terminal app.

Overview

CoolTerm is a simple serial-port terminal application (no terminal emulation) that is geared towards hobbyists and professionals with a need to exchange data with hardware connected to serial ports such as servo controllers, robotic kits, GPS receivers, microcontrollers, etc.

Features include display of received data in text or hexadecimal format, support for multiple concurrent connection (if multiple serial ports are available), the ability to send data in text or hexadecimal format, local echo, hardware (CTS, DTR) and software flow control (XON), logging of received data to text files, and more. Written in Xojo.

What's new in CoolTerm

Version 1.8.0.3.861:
New/changed features:
  • Replaced "Relative Time" timestamp format with "Time + Millis". It is now possible to record current time stamps with millisecond resolution, and the relative timestamp format is no longer necessary.
  • Renamed the "Absolute Date and Time" and "Absolute" timestamp formats to "Date and Time" and "Time", respectively.
  • Added code to improve accuracy for millisecond resolution timestamps.
  • Added option to add timestamps to received data displayed in the CoolTerm window. The timestamps are added to the actual data, i.e. they will also be present in hex view.
  • [Mac][Win] Added Preferences setting for smart display pausing. If enabled, scrolling up automatically pauses the display. Scrolling to the bottom automatically unpauses the display.
  • "PauseDisplay" is no longer a Connection Settings parameter.
  • Added "PauseDisplay(ID as integer, Value as boolean)" script command.
  • Added keyboard shortcuts to toggle RTS and DTR handshake lines.
  • Added "Remote" menu that is visible when the Remote Control Socket is enabled via the preferences. The menu item indicates if the socket is connected or not. The "Disconnect" menu item can be used to close and active connection.
  • Added context menu item to connection status label for an easy way to reveal the capture file.
  • Added button to "Save as Default" message dialog to open the default file location.
  • Selecting either the rated or maximum speed from the serial port information popup in the Serial Port Options, will set the baud rate to the selected value.
  • [Win] Added SPACE and MARK parity options (not supported on macOS or Linux yet).
  • [macOS] 32-Bit builds are no longer supported.
Improvements:
  • Added "GetFrontmostWindow as integer" script command.
  • [Mac] GUI tweak for better compatibility with macOS Big Sur.
  • [Win] Improved mouse wheel scroll performance.
  • Added better error handling when the remote control socket port or HTTP server port are already in use by another app.
  • Updated code for line mode history so that its behavior is consistent with UNIX style consoles.
  • Updated code to use use Serial Port API 2.0.
Bug fixes and stability imrpovements:
  • Fixed bug in the script engine that prevented serial port parameters from being updated when a script changes them via "SetParameter".
  • [Linux] fixed a bug that could sometimes result in bytes being lost during plain text to hexadecimal conversion.

Great app, thanks for making this available for free. I work a lot with embedded hardware and this is perfect for that. The hex view is especially useful. Thanks.

Not only is it LION compatible, but the ability to control it with applescript is great. A big improvement over my old terminal program.

This looks like a great alternative to DockLight on Windows. I look forward to trying it out. Maybe I will find myself with even fewer reasons to dual-boot my Mac.

This is an excellent piece of software that let my Mac keep in touch with my older equipment better than Terminal did.

Great app. After finding out that Zterm did not work with Snow Leopard and my USB to Serial adapter, I found out about CoolTerm... I use it to configure Cisco devices, and so far it's been working great. The only problem I found was that I can't recall previous entered commands by pressing the up arrow key. If this feature was added, then I'd give it 5 stars.

Great little app. Does what it says and useful for those who need this sort of thing. There are still lots of pure serial devices out there, and so for Mac types to try prototyping things this is a great help.
