Support for Windows PuTTY connecting straight to a local serial port

6 * TODO when porting to GTK 2.0:
7 *
8 * - GtkTree is apparently deprecated and we should switch to
9 * GtkTreeView instead.
10 * - GtkLabel has a built-in mnemonic scheme, so we should at
11 * least consider switching to that from the current adhockery.
