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.
