CuteCom is described as 'graphical serial terminal aimed mainly at hardware developers or other people who need a terminal to talk to their devices'. There are more than 10 alternatives to CuteCom for Windows, Linux, Mac, BSD and Cygwin. The best alternative is YAT - Yet Another Terminal, which is both free and Open Source. Other great apps like CuteCom are Tera Term (Free, Open Source), RealTerm (Free, Open Source), dterm (terminal emulator) (Free, Open Source) and minicom (Free, Open Source).
The idea is to create a simple and good looking terminal for being able to transmit to and from electronic boards and hardware. It can be configured to show data in hex or string format. It allows manual configuration of the port to use.
HyperTerminal is a terminal emulator capable of connecting to systems through TCP/IP Networks, Dial-Up Modems, and COM ports. Until Windows XP, it is included with the operating system, but, starting from Windows Vista, it has to be bought separately.
