Flash :: Connect Properly To Optivote Device Through Local Socket Connection?

Optivote IR8 is basically a voting system with a bunch of remote controllers, which can send IR signals to a receiver, which is connected to a computer through a USB port. And I'm trying to write my own little software for that with Flash.Optivote receiver communicates with software through a virtual serial port. When I connect to that port through PuTTY, I can see signals whenever I press any button on the remote controllers. Although, when I connect to that port through Serproxy (which relays a socket connection to a serial port connection), the remote controllers don't seem to work. I just get the same signal every half a second or so, over and over. I'm guessing the receiver is trying to make some kind of handshake this way.

The thing I can't figure out is what PuTTY does that Serproxy doesn't to make the serial port connection work. Maybe there's some proper way to tell the other end when I connect?(I use Serproxy, because Flash applications cannot connect to a serial port directly, but supports socket connections)
