Arguments
TERMinal speci
fies that a session startup message be sent to the socket, and a
command prompt is provided.
NONe disables
these features, allowing the server to be used for raw socket
transactions.
Examples
SOCKETServer:PROTOCol TERMinal sets the protocol to terminal, so that a
session startup message is sent to the socket, and a command prompt is provided.
SOCKETServer:PROTOCol? might return NONE, indicating that the protocol is
set to support raw socket connections.
*SRE
The *SRE (Service Request Enable) command specifies the bits in the Service
Request Enable Register. (See page 3-1, Registers.)

Arguments
<NR1> is an integer whose values can be 0, 16, 32, or 48. These correspond to the
following *SRE bits:
0 – service request is disabled
16 – request service when the MAV (message available) bit (bit 4) of the SBR
(status byte register) is true
32 – request service when the ESB (event status) bit (bit 5) of the SBR (status
byte register) is true
48 – request service when either the MAV or ESB bits of the SBR (status
byte register) is true
Other argument values may provide unexpected results.
NOTE. The power-on default for SRER is 0 if * PSC is 1. If *PSC is 0, the SRER
maintains the previous power cycle value through the current power cycle.

TEKSecure (No Query Form)
This command initializes both waveform and setup memories, overwriting any
previously stored data. These are the WFMInpre?, WFMOutpre?,andDATa
command values after the
TEKSecure operation.

Syntax
TEKSecure
Examples
TEKSECURE initializes both waveform and setup memories.
This is a program example of how to generate an SRQ when
TEKSECURE
completes:
# Bit 0 of t he DESE (Device Event Status Enable Reg ister)
# enables OPC to be repo rted to t he SESR (Standard Event
# Status Register)
DESE 255
# Bit 0 of t he ESER (Event Status Enable Register)
# enables OPC to be summ arized in the ESB (Event St atus #
Bit) of the SBR (Status Byte Register)
*ESE 255
# Bit 5 of t he SRE ( Service Request Enable Register)
enables
# the generation of SRQ when the ESB bit of the SBR
becomes # TRUE
*SRE 32
TEKSECURE;*OPC
When the TEKSECURE operation has completed, the OPC bit of the SESR will be
TRUE and SRQ will have been generated.
