Open Source Terminal Software

I have written on Open Source Telnet, SSH and RDP software before. Here is another open source terminal software.

Realterm is a terminal program specially designed for capturing, controlling and debugging binary and other difficult data streams. It is far better for debugging comms than Hyperterminal. It has no support for dialing modems, BBS etc – that is what hyperterminal does.



  • Text or Binary views of data
  • binary viewed as hex, 8 bit, 16 bit, little/big endian, signed, unsigned, special fonts
  • colorised: rx and tx data are different colors
  • ansi terminal or plain text or binary modes
  • protocol analyser / "port spying" mode
  • fixed frame sizes/line lengths
    sync patterns with masks and xors
  • data inversion
  • full remote control through active X/ Windows Scripting
    extensive command-line control
  • can be used for serial I/O component of other programs via activeX. Full support for minimize,hide,iconize, tooltray
  • special ascii+hex font to see hidden control chars
  • capture to file, settable capture size or capture duration
  • timestamping capture files for simple data logging
  • view and change control lines (cts,rts, dcd etc)
  • easy to send binary sequences
  • serial (comports) or telnet via tcp
  • arbitary baud rates
  • reset / power buttons for Pic Programmer
  • hideable to run in invisible or on tool-tray
  • can dump files to serial port
  • Drives I2C and SPI chips via BL233
