WorkMan HVS - IP Protocol

About

This protocol is our own protocol and can be used if no other protocol is in place.

The protocol works over TCP/IP and is linebased with CR+LF (#13#10) as a end of command terminator. WorkMan HVS can work both as a client and as a server so it's up to the hotelsystem to decide which way they prefer.

HS = Hotel System HVS = Our system (Hotel Växel System)

Commands

The first parameter is always the name of the command and the response to it always follows the form OK;<name of command> where OK is considered the command. The server/client should only send one command at a time and then wait for a response. If an answer hasn't been received within 10 seconds the connection should be considered down and a reconnect should be made.

Example:

HVS sends a welcome to a HS client that is connecting

 WELCOME;1

The HS-client responds

 OK;WELCOME
