SendData over RS232

Kommunikation über die RS23

Programmdownload


This program allows you to send lines of text over RS232.
Further you can send also only 1 Bit a time in hexadecimal format. If you use an USB-RS232 Converter it's enough to find the right COM-Port. You can test them all until you find the right one or look up in the Control Panel. On this screenshot COM7 is used.

What most times is forgot: A serial connection can only be used once a time. If you try to use it two time simultaneously the second program will give you an error-message. So close first the other program! Also non-existing-COM-Ports will give you an error-message.
