Section 5 Command Descriptions

5.53

OUTPUT (Controller mode)

The

OUTPUT

command sends data to the IEEE bus. The Remote Enable line is

first asserted if the Micro488/EX is the System Controller. If device addresses are

specified, those devices will then be addressed to listen. If addresses are not specified,

the Micro488/EX must already be configured to send data, either as a result of an

immediately preceding

OUTPUT

command or as the result of a

SEND

command.

If the character count,

count

, is specified then exactly that number of

characters will be sent to the bus devices. Otherwise,

OUTPUT

terminates data

transfer upon detection of a serial CR of LF terminator from the serial input. The

serial input terminator(s) are replaced with the bus output terminator(s) before being

sent to the bus devices.

The number of characters that can be set to a bus device is limited by the

available USER heap. The exception to this is OUTPUT #count, in which the number

of bytes is limited to 65,535.

The IEEE bus output terminators can be modified with the TERM command.

Refer to this command description for complete information.

addr

is a bus device address. Up to 15 addresses may be specified.

terminated by the serial

is specified in which case no

terminator is needed).
