Interfaces |
Description |
Doms POS Protocol |
This is a connection-oriented protocol. It is designed to communicate with a POS terminal where a constant connection is required. It also supports communication with typical Back Office applications. |
Doms Host Protocol |
This is a connectionless protocol (uses HTTP). It is designed to communicate with remote applications where a constant connection is not required. |
