This PPE is a transfer protocol selector (T-replacment). One of the few
1998 PPEs from Underground Empire that don't kick every other PPE's ass.
Still, it supports hotkeys, parameters and comes with protocol descriptions
for the most common file transfer protocols around (Z-Modem, S-Modem, Y-Modem,
BiModem, HS/Link and Zmodem/GifLink). Up to 50 protocols are supported. Some
protocols can be hidden, e.g. Y-Modem which is usually only used by the sysop
since it is an internal PC Board protocol and therefore required for local
file transfers.
