2 Software Application Interface

2.1 Control Interface Description

• 0xnn means a hexadecimal number.

•  means 0x0D 0x0A 0x00 on answers. On requests  could be one or more of the following codes/bytes: 0x0D, 0x0A, 0x00.

• The answers are only echoed to the origin source of the command (not to the other interfaces).

• The answer can by selected by concatenate the L command to the command. If no special answer is requested the file ack.ack will be sent back.

• The answer files can be edited and changed to your needs (see 2.12 Own skins and web interface).

• The standard answers are designed as XML.

• All strings and everything else are case sensitive.

• All commands are asynchronous to the stream.

• One command mustn't exceed 1024 bytes even it is concatenated.

2.2 Concatenate Control Commands

• To concatenate control commands use &. The commands will be executed from left to right in sequence (not parallel). The  must only be placed at

the end of the whole command and not after each separate command.

• To start talking and set volume to 12 use: c=83&v=12

• This is useful in the init sequence, in UDP commands or the define the answer. The init sequence is based on the serial command interface.

2.3 Formats supported

• Streams MP3, G.711 (uLaw/aLaw 8/24 kHz) and PCM (Motorola 16Bit 8/24 kHz).

MP3Pro files can be streamed but without the additional quality of MP3Pro.

• Encodes to MP3 (CBR and/or VBR depending on HW), G.711 (uLaw/aLaw 8/24 kHz) and PCM (Motorola 16Bit 8/24 kHz).

• The file extension of the audio file in the web application must be for uLaw 8 kHz u8, for uLaw 24 kHz u24, for aLaw 8 kHz a8, for aLaw 24 kHz a24,

for PCM 8 kHz p8, for PCM 24 kHz p24 and for MP3 mp3. All extensions are case sensitive except mp3.
