Action

Sends keyboard scan codes to the PC.

 

 

Syntax

SENDSCANKBD label | var

 

 

Remarks

Label

The name of the label that contains the scan codes.

var

The byte variable that will be sent to the PC.

 

The SENDSCANKBD statement can send multiple scan codes to the PC.

The label is used to specify the start of the scan codes. The first byte specifies the number of bytes that follow.

 

You can also send the content of a variable. This way you can send dynamic information.

You need to make sure you send the make and break codes.

 

The following tables lists all scan codes.

To emulate volume up, the data line would look like this:

 

DATA 5 , &HE0, &H32, &HE0, &HF0 , &H32

      ^ send 5 bytes

              ^ volume up
