Advanced Tab
Transparent: Allow raw communication between the Dial port and the TCP Connection.
Visa: Enable local Visa I engine. This will process one transaction, and issue an EOT after the transaction response has been
sent to the dial device.
Visa2: Enable local Visa II engine. After a transaction is complete and ENQ will be issued to query the next transaction in
sequence. If there is no response to the ENQ, then an EOT is issued.
Timer: Transparent Mode is the inter‐character delay (in milliseconds) used on the serial side to determine when a
remote device is finished transmitting. A low value may generate a faster response, but can send many TCP packets
and ‘fragment’ the serial data packets. A higher value will collect a larger amount of data into a single TCP packet, and
will generally keep packet boundaries more intact. Visa mode is unused. The recommended setting for this field is 150
for Transactions and 10 for some Streaming Protocols (ATM Management Protocols).
Data Mode: The following data mode is supported:
8N1: Data will be treated as full 8 bits valid. If the serial device is transmitting 7E1, then 7E1 formatted data will be transmit‐
ted to the TCP side.
7E1: Process data as if in 7E1 format. If the serial device is transmitting 7E1, then appropriate parity will be stripped/added so
that communication on the TCP side will be in 8N1.
The recommended setting for Transparent mode: As needed for various serial devices and TCP hosts.
The recommended setting for Visa mode: Leave this setting at 8N1. Automatic 7E1 detection is used.
Spoof ENQ: The recommended setting for this field is No.
Transparent Mode: This will enable an ENQ packet to be sent to the serial device to initiate a transaction. Up to 5 ENQ’s will
be sent while waiting.
Visa Mode: Unused. The Visa engine will automatically issue ENQ’s as needed, according to the Gwlnx config file.
No Rx Before Tx: Discarding data before transmitting in supported Message Mode. The recommended setting for this
field is No.
Transparent Mode: This will discard any data received from the serial side, prior to transmitting some data to the remote
serial device. This can be useful to discard initial line noise remnants from modem connections before an ENQ is issued (or
other start‐data message types from a TCP host).
Visa Mode: Unused. This is automatically enabled in the Visa engine, as it awaits a STX.
Disable Ack: Acknowledgement behavior in supported Message Mode. The recommended setting for this field is No.
Transparent Mode: Unused.
Visa Mode: Once a message is received from the serial device (ATM/POS) and the LRC is valid, this will disable sending an
ACK. Certain ATP/POS devices will fail if sent an ACK, and rather use the response message from the TCP host as an implied
ACK. Certain ATM/POS devices require an ACK before receiving the response message from the TCP host.
Pass Through Ack: Passing Acknowledgement in supported Message Mode. The recommended setting for this field is
No, unless using a SmartConnect device at the host processing side.
Transparent Mode: Unused.
Visa Mode: When an ACK is received from an ATM/POS device, pass that up to the host processor.
Enter IP Address 1 (Required): For coordination with SSL Connections, use 127.0.0.1. When using ANSWER mode, this
is a Client Primary IP address that GWLNX uses to connect to the Host server. When using DIAL mode, this field is not
used.
