If you want to be able to read utf data from your serial port, then you probably need to be using at least perl 5.8, and using the new "IO layer", ':utf8' on the open to set the filehandle to expect utf-8 data.

If your using Device::Serial, you probably aren't doing the open yourself, in which case you need to get hold of the filehandle being used (which appears to be available via $PortObj->{FD}) and use binmode to set the IOlayer to utf8 

use Device::SerialPort;

my $PortObj = Device::SerialPort( ... );
binmode $PortObj->{FD}, ':utf8';
...

Note: This is an educated guess. It's based upon my use of Win32::SerialPort (of which Device::SerialPort is an emulation), but I've no way to verify the speculation.

HTH.
