I have made level converter circuit for RS232 to UART using MAX232. But I'm stuck, because I don't know how to send data to MCU. Googling the problem tells me to use hyperterminal but that is not available in Win 8. Please tell me how to do it? I'm using Atmega8 to communicate with PC.

    \$\begingroup\$ An alternative for hyperterminal is PuTTY \$\endgroup\$ – jippie Jul 9 '13 at 14:12
  • \$\begingroup\$ @LeonHeller - no, software tools specifically needed for embedded hardware projects (of which a basic serial terminal would be an example, even though it once had other consumer uses) is explicitly on topic here. \$\endgroup\$ – Chris Stratton Jul 9 '13 at 18:57

Tera Term is an Open Source alternative to Windows Hyperterm. http://ttssh2.sourceforge.jp/index.html.en

Not sure if it runs on Windows 8 though.

    \$\begingroup\$ Putty is another alternative. It is also open source. The site doesn't highlight it's support of serial in addition to ssh & telnet, but it does support it. \$\endgroup\$ – Marko Jul 9 '13 at 9:31
  • \$\begingroup\$ @Psychic i checked this link and "requirements" tab inform me that this opensource can be used on win 8 also. Thanks a lot. \$\endgroup\$ – shafeeq Jul 9 '13 at 9:38
  • \$\begingroup\$ I ran it in Windows 8 just yesterday. It's pretty good for SSH too! \$\endgroup\$ – enthdegree Jul 9 '13 at 18:36

We're big fans of Terminal by Bray, it has many useful features such as being able to display / send data as raw hex (rather than just printable ASCII) and automated challenge/response, plus useful macros.

PuTTY is good as a user interface to something running Linux or similar, but Bray's is better for raw serial comms (non-human readable).
