Appendix A: Communications Driver

Communications Speciﬁcation 79

Appendix A:

Communications Driver

Compiling and Linking

The driver is compiled and linked with any Microsoft

™

compiler

version 5.1 or later. This code is probably compatible with many other C

compilers, but it has not been tested as such.

Include the ﬁle “def.h” in any module that contains calls to the driver.

Calls are explained in the Commands section below. A sample program

and makeﬁle have been included as a guide to using the

communications driver.

Compatibility

The Anafaze Communications Driver is compatible with the CLS and

MLS family of controllers. If you have a custom controller with custom

data table values, you can change or add entries in the

Set_Comm_Params() routine in “cmmd.c” to reﬂect the correct values.

Commands

The driver package consists of four commands:

• Init_Comm_Port()

• Close_Comm_Port()

• UpLoad()

• DownLoad()

This appendix covers only the usage of these commands. Setting up

data, an interpreting status byte, etc., is covered in the Anafaze/AB

Protocol chapter in this manual.

Init_Comm_Port()

Use Init_Comm_Port to open and initialize the comm port that is

desired for communications.

BOOLEAN Init_Comm_Port(unsigned int com_port, BOOLEAN

hi_baud, char error_check);

unsigned int com_port; This is either COM1 = 0, or COM2 = 1.

BOOLEAN hi_baud; Set TRUE for 9600 baud, or FALSE for

2400 baud.
