Kaulquappe Posts: 3093 Rating: (324)	Hello Aruns, the outputs of BSEND and BRCV are displayed dynamically. You can't watch them when going online. You must evaluate them in your program. Save STATUS when ERROR=TRUE. I recommend to insert two counter for the edges at DONE and ERROR. Regards, Kaulquappe
