Creating Custom Serial Port Messages

6–6

The Define Serial Port menu consists of two items:

• Erase Port Data

• Buffer: Wait/No Wait

Erase Port Data

Picking the Erase Port Data box permanently removes all defined strings

from the selected serial port.

Note: Do not pick this box if you value any portion of your serial port

strings or parameters.

The Erase Port Data function is useful if you want to clear all the contents

for a serial port, such as if you need to entirely redefine all strings, and not

merely edit them, or if the serial port messages are no longer useful for your

application, and you want to free up the CVIM module memory for other

uses.

To use the Erase Port Data function:

• Pick the Erase Port Data box. Picking the Erase Port Data box once

displays this warning message:

• To permanently remove the port data, pick the Erase Port Data box a

second time. If you do not want to erase the port data at this point, pick a

different menu item instead of the Erase Port Data box.

Buffer: Wait / No Wait

Use the Buffer: box to select one of two options for transmission of serial

messages – Buffer: Wait and Buffer: No wait.

Buffer: box
