Maurizio,

Try this:

define GENERIC_READ 0x80000000

define OPEN_EXISTING 3

define FILE_ATTRIBUTE_NORMAL 0x00000080

...

local hIn := CreateFile( "COM8:",; // change the number as needed
GENERIC_READ, 0, 0, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL )

Thanks Antonio, now it works.

When I started the aplication I was afraid of using a new product on an aplication with a so sort time limit. But now everything is ok

Jose,

We are glad to know we are moving forward

Thanks to all of you for your feedback and support,
