CoolTerm 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 version 2.2.0.3.0.1327

New features:
  • Added XMODEM and YMODEM file transfer protocols.
  • Added support for keyword formatting.
  • Introducing new file extension (.cooltermsettings) for settings file to avoid conflict with the OpenOffice Spreadsheet Template file type. Files with the legacy extension (.stc) will still be compatible. This includes existing default.stc files.
  • Added "Case Sensitive" to keyword formatting options.
  • Added option to modify the timestamp separator for timestamps added to received data.
Enhancements and fixes:
  • Fixed bug that would force transmit macros in the default settings on loaded settings that already have their own sets of macros specified. The same bug could also result in duplicated macros restored sessions that include unsaved settings.
  • Fixed bug that could crash the app at startup when certain remote control socket errors occur (rare).
  • Fixed bug that would cause timestamps in a localized format (selected via the Preferences) being added with an incorrect text encoding, resulting in unexpected characters being included in the timestamps.
  • Fixed bug that would display the Macro settings page in the Options window when "Font Settings" is selected via a context-click in the plain text or hex display.
  • [Linux] Playing sounds no longer crashes on newer versions of Linux (like Ubuntu 23.10), or Raspberry Pi5.
  • [Win] Enumerating serial devices no longer causes the serial ports to be temporarily open.
  • [Win] Fixed bug that prevented TAB keypresses from being entered into text fields that should allow them.

Hi, I download the app but when I try to open it, it shows "“CoolTerm.app” can’t be opened because Apple cannot check it for malicious software. Did I miss something in the installation?

Very clean, nice app. One thing I cannot get to work: xmodem a text file to a Pico running PicoMite, an MMBasic interpreter (PicoScope project in MAKE vol.87). CoolTerm easily connects to usbmodem1423301 (9800, 8, N, 1 no flow), gets the PicoMite prompt > , apparently transmits the PicoMite command xmodem receive, responding with a new line and a couple of dots, then waiting for a file, which seems to transmit over several seconds, all 13K bytes. Everything looks OK but then: Error: Remote did not respond. I assume the problem is with PicoMite whose docs say xmodem file transmission was tested only with TeraTerm under Windows. I can transmit the PicoMite.bas file to the Pico board using Windows 11 Home running on my iMac under Parallels 19 so I have completed the project. I'm assuming that MMBasic is not returning something which CoolTerm needs.

I'd just like to say thanks for making this App free. I deperately need to monitor two USB comm ports simultaneously; allowing me to interact with two separate MCU devices at the same time whilst they communicate via I2C in the background. In fact they seem to be having some trouble; so I need to view the debug on both at the same time to see whats going on.
