RS-232 serial control

Introduction

The interface is based on RS-232 using 115200 Baud, 1 start bit, 1 stop bit and no parity.

Protocol

The protocol is line-oriented. The controller expects single command lines containing a

command word - optionally followed by one or more parameters, each separated by one or

more spaces. Command lines must be terminated by a single carriage return (ASCII code 13)

and may be optionally followed by a linefeed (ASCII code 10).

Command words as well as parameter words are case-sensitive. They may be abbreviated.

The controller will respond to command lines with a status message, which starts with a three-

digit response code, followed by a human readable text, which further describes the response

code. In addition, some status messages may be sent at any time.

In response to some commands the controller may send multi-line responses, where the first

message line starts with the number 3. The last line of a multi-line response will contain a

single period only.

When powered up, the controller will send an initial welcome message, which includes the

firmware version and the serial number.
