This daemon makes GVRP announcements of all VLAN interfaces on a FreeBSD system. GVRP is the GARP VLAN Registration Protocol, defined in IEEE 802.1Q (VLANS). GARP is the Generic Attribute Registration Protocol, defined in 802.1D (bridging). The protocol allows switches or trunked end stations to announce to the network what VLANs should be forwarded to that device. The effect is that VLANs only need to be configured on the member ports; the protocol figures out which trunk ports are effectively also members. The daemon just announces the VLANs statically configured on each interface to that interface. It does not listen for inbound GVRP announcements.
dterm is a simple terminal emulator which doesn't actually emulate any particular terminal. Mainly, it is designed for use with xterm and friends, which already do a perfectly good emulation. Therefore, it doesn't need any special help; dterm simply provides a means by which keystrokes are forwarded to the serial line, and data forwarded from the serial line appears on the terminal.
5x9 and 5x10 are two X11 fonts intended for use with xterm or other programs requiring readable small fonts. At only 5 pixels wide, they are particularly well suited to small laptop screens, allowing two 80 column windows side by side on an 800x600 screen (albeit with no room for window frames), or three windows across with room to spare on a 1280x1024 screen. The fonts implement VT100 line-drawing characters. Bolding is not directly supported; xterm does adequate bolding by duplicating pixels.
