Serial Comms in 4.6.4

Dar ,

Windows 7

All hardware has been checked okay.

When using read from driver in scripts loaded into 4.6.4 or standalone from
4.6.4 nothing is read ?

The identical script loaded in pre-windows  7 Livecode releases work.

Thanks
Camm

Hi, Camm!

I don't remember any changes.

Maybe this can be tracked down.  What OS?  How does it fail?

However, you might want to rule out other things.  I find the most common
reason that a serial communications program suddenly fails is a cable issue.
Usually the handshake lines don't make it trough or something else is wrong
in the wiring.  Sometimes the USB-to-serial adaptor is an issue.
