Galil Software Tools And Libraries - Galil Motion Control DMC-14 5 Series Manual

When hardware handshaking is used, characters which are generated by the controller are placed in a
single character buffer before they are sent out of the controller. When this buffer becomes full, the
controller must either stop executing commands or ignore additional characters generated for output.
The command CW,1 causes the controller to ignore all output from the controller while the FIFO is
full. The command, CW ,0 causes the controller to stop executing new commands until more room is
made available in the FIFO. This command can be very useful when hardware handshaking is being
used and the communication line between controller and terminal will be disconnected. In this case,
characters will continue to build up in the controller until the FIFO is full. For more information, see
the CW command in the Command Reference.

Galil Software Tools and Libraries

API (Application Programming Interface) software is available from Galil. The API software is
written in C and is included in the Galil CD-ROM. They can be used for development under
Windows environments. With the API's, the user can incorporate already existing library functions
directly into a C program.
Galil has also developed an Axtive-X Toolkit. This provides 32-bit OCXs for handling all of the
DMC-14x5 communications. These objects install directly into Visual Basic and are part of the run-
time environment.
