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 (bookingsystem)
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
Common variables
<protocolversion> means what version of the protocol that support this. The current version is 1 only.
<roomid> the actual roomid that exists in the HS. Roomid of R1234 might have a extension 1234 in the PBX but might also be completely different. This is the roomid of th HS!
