I have a machine that measures, after measuring sends an impression with some readings to a printer connected directly to this machine, I need to read this data instead of the printer

Hi Cleaver;

A serial port or USB device can be read or written to using the FileOpen ( ) method. For example ...

integer li_FileNum

li_FileNum = FileOpen ( "COM1:", LineMode!, Write!, LockWrite!, Replace!)

FileRead / FileWrite ...

Just replace COM1: with the device name / port you need to access

HTH

Regards ... Chris

It would be helpful if you told us the name/model of device (and a link to the device manufacturers website) and how it connects to the pc (USB, Serial Port).
