Q. In the manual you mention controlling the RTS and DTR lines but I am unable to figure it out. How do you accomplish it with your program?

A. There is a status indicator in the bottom right corner of the program window. It shows status of RTS, DTR, CD , CTS, DSR and RI signals. Double click on it to open a window with status of each signal.

Q. If I have something plugged into com 1 and want to trap it with your product, then your product cannot connect. If I unplug from com port then your program will connect to that port but now what I plug into that port cannot connect.

A. Look RS-232 has no functionality to intercept data from stream. It can send data to COM port any receive reply. If your program has already opened (initialized) the port, Look RS-232 will fail to do it and vice versa.

Q. I wrote a macro string, which I want to be terminated by the char "carriage return" (ASCII code 0dh). When I press the return button on the keyboard, the expected char will not be added to the macro string, but the macro will be finished. How can I add any ASCII code?

A. Look RS-232 can send data entered as symbols (CHAR) as well as entered as BIN, HEX, OCT and DEC. If your case, if you need to send "carriage return" (ASCII code 0d h), you need to enter h 0d. If you need to send text, enter it in quotation marks ("Hello Word" , h 0a 0d). See example.

Q. It seems that I cannot get more than 8 characters to display on a given line regardless of configuration. Can you suggest what I may be missing?

A. You can change width of info field from 4 to 32 characters. See screenshot.

Q. When I connect a scope to the transmit line on my serial port, two stop bits are sent no matter what setting I choose (1, 1.5, or 2). Is there a way I can fix this?

A. According to specification stop bit with size 1.5 is used only for words of 5 bit length. If attempt to open port with incorrect settings is made, system error is displayed.
