Section 4 Serial Controller

4.85

TERM

The TERM command sets the end-of-line terminators for output from the

Analyzer488 to IEEE 488 bus devices. All output to bus devices, except

OUTPUT

#count

, is terminated by the IEEE 488 bus output terminator. All

ENTER

input

from bus devices is terminated on a Line Feed (LF) or optionally specified with the

ENTER

command.

During

OUTPUT

, the Analyzer488 takes the data it receives from the user's

program, strips all CR and LF characters from it (except

OUTPUT

#count

) and

appends the IEEE 488 bus output terminator before sending it to the bus device. The

default terminators for output are factory set to

, which is appropriate for most

bus devices.

EOI

has a different meaning when specified for input than when it is specified

for output. During input,

EOI

specifies that input will be terminated upon detection

of the End Or Identify (EOI) bus signal, regardless of which characters have been

received. During output,

EOI

specifies that the EOI bus signal is to be asserted during

the last byte transferred.

The query command

TERM?

returns the current IEEE 488 bus terminators.
