Measurement Computing Micro488/p - Manual (Page 30)

3-12 09-27-02 Command Descriptions
<CTRL>A ESCAPE
The system command ESCAPE unlocks the Micro488/p from an inappropriate command,
such as a command requesting data from a nonexistent device.
When the ESCAPE command is received, the serial handshake line (RTS) is un-asserted. It
is asserted when the Micro488/p is capable of buffering commands. If XON/XOFF
handshake is selected, the software handshake state is not modified.
Issuing the ESCAPE command clears the serial input (pending commands) and causes the
Micro488/p to wait for new commands.
