How to write 'Enter' key to serial port COM1 ?

[wuligang]

Hi Guys,

I want to use VISA write to send the 'Enter' key to the serial port.

How can I do this??

The command I need to send is like  COMMAND+enter key

I tried to add the \r after the command but it didn't work. Could

anyone give me some clue on this? Thanks a lot.

First, make sure that your text control/constant is set for '\' Code Display. Otherwise you are sending the characters "\" and "r". You might also have to send \n i.e. \r\n.
