5.4 Communicating with legacy controllers

The ICM interface between used by MintMT is not compatible with older versions of ICM used by other

versions of Mint.

5.4.1 Serial controllers

Normally all MML functions called by the MintMT ActiveX control use the ICM protocol. This is only

supported by MintMT controllers. In order to communicate to with a non-MintMT controller the ASCII

comms protocol must be used.

Note: This protocol can only be used to read and write to the comms array on the controller.

The elements of the comms array are accessed by the functions getComms and setComms. The protocol

used by these functions can be changed using the function setCommsANSI328Mode. This function

accepts a boolean parameter.

Passing true will enable the ASCII comms protocol and all future use of the functions getComms and

setComms will use the ASCII comms protocol.

Passing false will disable the ASCII comms protocol and all future use of the functions getComms and

setComms will use the ICM protocol.

5.4.2 Dual Port RAM controllers

In order to communicate with a Dual Port RAM controller running a older version of Mint the comms array

can be used.

On these controllers the comms array exists within the locations 01D6 (hex) to 029B (hex) of Dual Port

RAM and is an array of floating point values. The functions getFloat and setFloat can be used to

access this area. Comms values are only written to even locations.
