Writing Commands to Robot Through Serial Port

    Hello,
    I am attempting to write commands directly to my robot through serial port communication using an external program. I have seen on other posts that it is possible, however, I do not know how to format the commands themselves. Do I send lines of KRL directly or do I format commands such as x,1,y,3, etc? Thank you

    Well, first off, what model controller is this, and what version of KSS are you running?

    It's not possible to send program commands to a KRC via the serial port, in the sense of a Telnet session on a computer. However, it is possible to create a program in the robot that will listen to incoming ASCII strings and parse them into variables, which can then be used as motion coordinates, speeds, etc.

    My apologies. I meant to include my robot info but obviously I forgot. I have a KRC2 running KSS5.x. Thank for clarifying this for me. So basically I could write a program that loops over and receives input from an external program through COM socket to tell it where to position the robot?

    Essentially, yes. The devil is in the details, but it is doable. Often, due to timing/handshaking issues, I find it easier to set up the remote computer as the "server", and have the robot act as the "client" -- that is, rather than the robot "listening," it sends out a request for instructions when it's ready and able to accept said instructions. So,
    Open Port.
    Send command request string.
    Get response string back.
    Close port.
    Parse string into usable variables.
