10. Appendix A: Message negotiation
“Send ENQ”, “Use SYN/SYN/SYN”, “Send ACK” all disabled
By default, the three settings covered under this topic (“Send ENQ to terminal to initiate transmission”, “Use SYN/
SYN/SYN preamble to establish connection”, and “Send ACK to terminal after each received message”) are dis-
abled. This means that by default the PayLink-IP/232 operates transparently, passing all negotiation messages
directly between the terminal and the payment server.
