The default value for each of these commands is zero, and resetting the modem will restore t
default settings.

What are the general guide
lines that have to be followed for setting up a Dial to TCP converter
device in VeriCentre?


When you use a dial to TCP converter device (like the Cisco
5300 or Cisco
5350 or HyperCom NAC
device) with VeriCentre, please follow the guidelines give
n below:

* Data transparency

The concentrator device should NOT act on any data characters. This
includes turning off "Data forwarding Character" and "Software Flow Control characters" on the
concentrator device. This also means that the
concentrator device should NOT send ENQ on its own
to the POS at the beginning of the download.

* One TCP connection per download

Each dial download request results in a new TCP/IP
connection being opened to VeriCentre server to the port 801
3(configurable), and the VeriCentre
download packets should be TRANSPARENTLY tunneled through this new TCP/IP connection. At
the end of a terminal download session, this TCP/IP session is disconnected.
