176TODO: PASV command will not work for IPv6. RFC2428 describes
177IPv6-capable "extended PASV" - EPSV.
178
179"EPSV [protocol]" asks server to bind to and listen on a data port
180in specified protocol. Protocol is 1 for IPv4, 2 for IPv6.
181If not specified, defaults to "same as used for control connection".
182If server understood you, it should answer "229 <some text>(|||port|)"
183where "|" are literal pipe chars and "port" is ASCII decimal port#.
184
185There is also an IPv6-capable replacement for PORT (EPRT),
186but we don't need that.
187
188NB: PASV may still work for some servers even over IPv6.
189For example, vsftp happily answers
190"227 Entering Passive Mode (0,0,0,0,n,n)" and proceeds as usual.
