eot - Enable/Disable END Message on GPIB
Writes
Initialization function
eot
Syntax:
Purpose: You use eot at the beginning of your program if you
wish to change how the GPIB-MAC terminates GPIB
writes. Using eot, you tell the GPIB-MAC to auto-
matically send or not send the GPIB END message with
the last byte that it writes to the GPIB.
Remarks: If the argument boo1 is 1, the GPIB-MAC automatically
sends the END message with the last byte of each wrt.
If the argument boo1 is 0, END is not sent. The power-
on default is 1.
If you call eot without an argument, the GPIB-MAC
returns to you a 1 to indicate END termination is
currently enabled, or a 0 to indicate END termination is
currently disabled
The assignment made by eot remains in effect until you
call eot again, call onl, or you turn off the GPIB-MAC.
The GPIB-MAC sends the END message by asserting
the GPIB EOI signal during the last byte of a data
transfer. eot is used primarily to send variable length
data.
Refer to the GPIB Read and Write Termination
explanation in Section Three.
