SEND

Sends messages on the IEEE-488 bus.

SEND dest ;message [message ...]

Usage:

SEND 7;UNL MTA LISTEN 2 DATA "Bye" END

SEND @Gpib;UNL MLA TALK Primary CMD 24+128

Description:

The SEND statement sends low level IEEE-488 commands and data bytes. IEEE-488 commands are sent with the ATN line asserted; whereas data bytes are sent without the ATN line asserted. The computer must be the active controller to use CMD, TALK, UNT, LISTEN, UNL, SEC, MTA or MLA. Any talk addressed device may send DATA.

Message	Action Taken
CMD	Sends the expression values as command bytes. CMD with no items asserts the ATN line.
DATA	Sends the expression values as data bytes. If END is added, EOI is set on the last data byte.
LISTEN	Sends the expression values as listen address commands.
MLA	Sends the Interface's Listen Address command.
MTA	Sends the Interface's Talk Address command.
SEC	Sends the expression values as secondary address commands.
TALK	Sends the expression value as a talk address command.
UNL	Sends the unlisten command.
UNT	Sends the untalk command.
