I have a POS printer in COM1 port.
I want to send control codes to it without using OLE or
DOS commands. I read Ed Rauh article in KB about sending data to printer.
I ran the following program according to this article.
However, this sends incorrect data, probably baud rate is wrong. Print test
page works correctly.

Why? How to send control codes to COM1: port directly from VFP?

DECLARE INTEGER CopyFile IN KERNEL32.DLL ;
STRING @SourceFileName, ;
STRING @DestFileName, ;
INTEGER bFailIfExists

? CopyFile( 'C:\AUTOEXEC.BAT', 'COM1:', 1)
