I updated psc to include SOCKS4 and SOCKS5 support, so you can now do crazy things like web browsing remote networks from within a modem dialup shell or portshell (even multihop), effectively upgrading a simple portshell to a SSH like e2e pty shell with the ability to forward TCP and UDP ports.
This finally merges code into PSC that I started back in early 2000's, when I was in need to have TCP connections via modem dialups that actually did not have ppp to obtain an IP address to browse from.
