Socket gateway configuration utility: setVPSoption
This utility allows you to configure the two ports of the Socket
Gateway to either remove the echo commands (VPS) or leave the
data unaltered (NONVPS).
If you are a DT61xx or DT65/75/90 non-LCDS customer, configure
both ports as NONVPS. DP1xxxEPS and DT 75/90 customers
using LCDS need to decide whether to configure one or both ports
as VPS. If a port is not being used, it is recommended to set the
port to NONVPS.
The Socket Gateway allows two ports to be configured at one
time. Regardless of the port number assigned on the Socket
Configuration Utility, the socket port configured on the first port is
always Port 1, and the second line is always Port 2. Both ports are
set as VPS upon installation. set as VPS upon installation. Syntax
of the utility:
