I`m trying to operate my PLC(CPU314) with Hyper Terminal
via CP340. I can send information from the PLC to the Terminal and it works fine.
The problem is that it doesn`t work the other way around as it should; when is send a set of characters, for example the word "perkele" it is received only in the first receiving byte character by character and not as a full word in all of the receiving bytes, why is this happening?

I`ll attach a picture to show what I mean.

In the hardwareconfiguration for the cpcard under Parameter-->Protocol you have settings for how you want to end recived message. You probably have On exipiry of character delaytime activated. Change to end character CR (carriage return) that way message will be "received" when you press enter
