Hi,
I've installed both 1.47 and 1.49 versions binary.

If I try on COM1: on a IAR demo board all works well. If I try with a
FTDI Usb converter (a DLP board), I get an error 5 during the COM3:
port open.

The same circuit works with no problems with the Philips's Flash
Utility and with a simple VB6 program that I've written to connect and
erase che chip.

The FTDI USB converter with the virtual port diver is supported?

Thanks.
