7. Programmer's Reference
ASCII
When the router receives a message, the next message will be sent to the controllers:
Ȩ (S#In=[received text])
or
Ȩ (S#On=[received text])
where n is the port number, I is the input, and O is the output port. See the example:
Far endpoint sends: Simple math: 2\[3-(2+8)]. Solve it!
The router sends:
Ȩ (S#I1=Simple math: 2\\[3-\x282+8\x29]. Solve it!)
The received data is represented as plain ASCII text and the maximum length of it is 54 bytes. The ( and
) characters are frame delimiters, so they cannot be inside a message. Therefore all ( characters will be
replaced to \x28, while all ) will be replaced to \x29 escape sequences, while \ will be escaped as \\. No other
characters will be escaped. If the programmer of the controller does not want to parse escape sequences (it
is in fact just a sprintf(...) function call), the Binary mode should be used.
Binary
Ȩ (B#In=[received text as binary data, e.g. 736F6D657468696E67])
or
Ȩ (B#On=[received text as binary data, eg. 736F6D657468696E67])
where n is the port number, I is the input, and O is the output port.
The received text is translated to binary form. The maximum length of the received text is 54 bytes, so the
length of the hex data can be up to 108 characters. See the example:
Far endpoint connected to input port 1 is sending data, the router sends:
Ȩ (B#I1=736F6D657468696E67)
7.12.3. Querying the Serial Parameters
The properties of the serial pass-through can be queried on the input and the output side.
Command and Response
ȩ {:SERIAL#<in2/out2>@<S>I/O=?}
Ȩ (SERIAL#<in2/out2>@<S>I/O=<a>;<b>;<c>;<d>)CrLF
Example
ȩ {:serial#24@so=?}
Ȩ (SERIAL#24@SO=1;9600;1;1)CrLf
Serial pass-through sending and receiving is enabled on the 24th output port with 9600 baud.

7.12.4. Setting the Serial Parameters
The properties of the serial pass-through can be modified on the input and the output side.
Command and Response

Ȩ (SERIAL#<in2/out2>@<S>I/O=<a>;<b>;<c>;<d>)CrLf
Example
ȩ {:serial#24@so=1;9600;1;1}
Ȩ (SERIAL#24@SO=1;9600;1;1)CrLf
Serial pass-through sending and receiving is enabled on the 24th output port with 9600 baud.
