Re: serial communication

This is a discussion on Re: serial communication within the labview forums in Programming Languages category; I have two suggestions:   (1) Try writing the string without using the concatenate strings function. If you have all inputs as constants, then why use the function???:smileywink:   (2) Try using the carriage return constant in the strings palette instead of a \r\n string.   I would try the one that you claim works by wiring the constant that you have on the block diagram to the VISA write function instead of the control.. Does it still work??   I hope this sheds some light....
