This is used to write strings to a COM port, a typical use is to send to the information to an external software or device.
The string to set the port is as follow:
‘PortName:Speed,Parity,Bit,Control’.

This statement is manually written without user interface.

$$Begin Example

DECL/CHAR,10,my_var
DECL/INTGR,ii
my_var=ASSIGN/'Here the value assigned!'

$$Open the COM port

DID(my_com_device)=DEVICE/COMM,'com3:9600,n,8,1'
OPEN/DID(my_com_device),DIRECT,INPUT
DO/ii,1,10,1
WRITE/DID(my_com_device),'Here the String WRITTEN directly!!'
WRITE/DID(my_com_device),my_var
ENDDO
$$Closing the Port
CLOSE/DID(my_com_device)
