I agree it is nice little program, but when a lot of data is sent it often crashes..

It it great program to test simple stuff but for anything more advanced or when more data is sent you need some advanced terminal such as
http://docklight.de/
or similar..

Docklight is also RS232 terminal program, but it also has TCP/UDP terminal.
And one cool thing is its adaptive macros with joker characters
Same as in terminal.exe you mentioned, but you can change some part of the macro each time it is sent.
For example if it is defined as
CONFIG=**\n\r
then when you send that macro string to serial port you are prompted each time for ** part of the macro, while the rest of the string is sent automatically.

Useful when naving commands to send in terminal to microcontroller or some other device :)
