Section 5 Command Descriptions

5.10

Sending the system command

causes the Micro488/EX to return to power-on

conditions. Serial input (pending commands) and serial output (pending data) are

cleared, and any software programmable terminators are returned to the power-on

conditions. If a macro has been assigned as the

STARTUP

, it will execute immediately

upon command completion. Macro and log buffers are not effected by this command.

This is the only command which does not require a serial terminator to execute.

Reset is executed upon receipt of the second

When the

command is received, the serial handshake line (

RTS

) is un-

asserted. It is asserted when the Micro488/EX is capable of buffering commands. If

XON

XOFF

handshake is selected, the software handshake state is reset and an

XON

character is transmitted when the Micro488/EX is capable of buffering commands.

The

character, referred to as the '

' character, can be changed or disabled by

using the

command. If it is anticipated that the

character may be part of the

data

within an

OUTPUT

SEND

command, it should be disabled.
