Problem for the TUL installation

[Choli]

Hello,

I need some help setting up my TUL component with Windows 7 (32-bit) configuration
I tested for 1 week: without success.

The steps I followed:
1-Installing Firmware for TUL "TPUARTtransparent.hex" with the Flip tool: OK result
2-Installing Windows drivers "LUFA USBtoSerial.inf" (TPUART series with CDC-ACM port): result OK on COM3
3-Installation of Perl (Active Perl 5.16.3.1603): OK result
4-Installation of Win32-Serial Port (Win32-SerialPort-0.22.tar.gz) of http://www.fhemwiki.de/wiki/Windows_-_FHEM_installieren FHEM_unter_Windows_7_installieren #: Pb on tests with the "command perl Makefile.PL testPort = 3 "
5-Installation of FHEM (FHEM-5.4-fb7270): OK
6-Setting "fhem.cfg"
7-Launch FHEM "fhem.pl fhem.cfg
"The following error occurs:" COM3 protocol is not supported " : Detail in the log file.

On the command line:
Use of uninitialized value in string eq at ./FHEM/00_TUL.pm line 843. <$fh> line  7.
Use of uninitialized value in string eq at ./FHEM/00_TUL.pm line 894. <$fh> line  7.

And if I test the ignition of my lamp 1 with the web application, I have the following message:
SimpleWrite data: 1
Use of uninitialized value in string eq at ./FHEM/00_TUL.pm line 868.
Use of uninitialized value in string eq at ./FHEM/00_TUL.pm line 878.

I tested with several COM ports and multiple machines (WIN XP, Vista) without success.
Could you help me?

You will find the details attached.
Thank you in advance for your help
Christophe
