Question Kindle's USB Serial Gadget: What is it?

The Kindle came with three USB gadget drivers. g_file_storage (connecting Kindle to computer as a storage drive), g_ether (USB networking), and g_serial (no idea). I got g_serial to load by doing the following through SSH:

Code:
rmmod g_ether; mknod /dev/ttygserial c 127 0; rmmod arcotg_udc; rmmod charger; modprobe charger; modprobe arcotg_udc; modprobe g_serial use_acm=1;
(According to diags script, use_acm=1 if windows, use_acm=0 if unix/linux)
Everything has to be in one line, because only one gadget driver can be loaded at a time, loading serial will disable USB networking/storage until restart. I plugged it into my Windows machine and installed drivers with the following directions: http://www.mjmwired.net/kernel/Docum...get_serial.txt

Got COM3, connected with Putty, then... nothing.

Anyone got this working, and if so, what does it do (my guess is USB interface for the TTL port).
