  • Configurable input mode.
  • Single-line text commands; multi-line text commands; files.
  • Unlimited number of predefined commands; history of recent commands.
  • Escapes for bin/oct/dec/hex like "\h(4F 4B)" as well as C-style "0x4F" and "0b01001111".
  • Escapes for ASCII controls like "<CR><LF>" as well as C-style "\r\n".
  • Special commands like "\!(EOL)", "\!(NoEOL)", "\!(Delay)", "\!(LineDelay)", "\!(LineInterval)", "\!(LineRepeat)".
  • Option to automatically trigger an action.
  • Option to automatically trigger a response.
  • Versatile monitoring and logging of sent and received data.

User Reviews

  • Excellent terminal to Embedded Devices Debugging.

  • Best terminal on Win 7

  • Really amazing piece of software. I love the interface, support for UART and TCP/IP, being able to save a configuration, the logging facility (once I discovered it...) and user defined messages. The only thing that is really lacking is the ability to open a UART port in spy mode (unless I'm missing something?). It is surprisingly useful to monitor a UART link without interfering.

  • Best Terminal application I found in years. Great USB HID terminal App .
