TermT *term,BOOL reserved, LPDWORD compStat);
Send Send (int board, short address,char data[],long

data[], long count, int eotmode)
Usage Notes
OutputX is no longer to be used. The OutputX command was used to send data to an
interface or external device. The Remote Enable (REN) line was first asserted, if Driver488 was
the System Controller and AutoRemote was enabled. Then, if a device address (with optional
secondary address) was specified, Driver488 was addressed to Talk and the specified device
was addressed to Listen. If no address was specified, then Driver488 had to have been
previously configured to send data, either as a result of a preceding OutputX command, or as
the result of a Send command. Terminators were automatically appended to the output data as
specified.
Also See: Output, OutputN, OutputMore, and OutputNMore, which are short-form
versions of the OutputX function.
Send is used to send data to one GPIB device. When this routine is executed, the specified
GPIB board is addressed as a Talker, the designated GPIB device is addressed as a Listener and
the number of bytes (specified by count) in data is sent.
Values for eotmode are as follows. The constants are defined in the header file.
o NLend — Send NL (Line Feed) with EOI after last data byte.
o DABend — Send EOI with the last data byte in the string.
o NULLend — Do not mark the end of the transfer.
In the example, GPIB board 0 sends an identification query to the GPIB device at address 3.
End of data is signalled by an EOI.
Example:
Send (0, 3, "*IDN?", DABend)
