The Virtual Serial Port must be correctlyenabled and configured in the host RBSU. You can access the Virtual Serial Port using SSH or telnet (ifenabled). You can access the CLP from a host serial session if the UART and Virtual Serial Port share thesame settings. To access the CLP from a host serial session enter Esc( (escape left-parentheses) to switch tothe command-line interpreter.Pop-up blocking applications will prevent the Remote Serial Console option from running.
