+\S2{using-cmdline-loghost} \i\c{-loghost}: specify a \i{logical host
+name}
+
+This option overrides PuTTY's normal SSH host key caching policy by
+telling it the name of the host you expect your connection to end up
+at (in cases where this differs from the location PuTTY thinks it's
+connecting to). It can be a plain host name, or a host name followed
+by a colon and a port number. See \k{config-loghost} for more detail
+on this.
+
+\S2{using-cmdline-hostkey} \i\c{-hostkey}: \I{manually configuring
+host keys}manually specify an expected host key
+
+This option overrides PuTTY's normal SSH host key caching policy by
+telling it exactly what host key to expect, which can be useful if the
+normal automatic host key store in the Registry is unavailable. The
+argument to this option should be either a host key fingerprint, or an
+SSH-2 public key blob. See \k{config-ssh-kex-manual-hostkeys} for more
+information.
+
+You can specify this option more than once if you want to configure
+more than one key to be accepted.
+
+\S2{using-cmdline-pgpfp} \i\c{-pgpfp}: display \i{PGP key fingerprint}s
+
+This option causes the PuTTY tools not to run as normal, but instead
+to display the fingerprints of the PuTTY PGP Master Keys, in order to
+aid with \i{verifying new versions}. See \k{pgpkeys} for more information.
+
+\S2{using-cmdline-sercfg} \i\c{-sercfg}: specify serial port
+\i{configuration}
+
+This option specifies the configuration parameters for the serial
+port (baud rate, stop bits etc). Its argument is interpreted as a
+comma-separated list of configuration options, which can be as
+follows:
+
+\b Any single digit from 5 to 9 sets the number of data bits.
+
+\b \cq{1}, \cq{1.5} or \cq{2} sets the number of stop bits.
+
+\b Any other numeric string is interpreted as a baud rate.
+
+\b A single lower-case letter specifies the parity: \cq{n} for none,
+\cq{o} for odd, \cq{e} for even, \cq{m} for mark and \cq{s} for space.
+
+\b A single upper-case letter specifies the flow control: \cq{N} for
+none, \cq{X} for XON/XOFF, \cq{R} for RTS/CTS and \cq{D} for
+DSR/DTR.
+
+For example, \cq{-sercfg 19200,8,n,1,N} denotes a baud rate of
+19200, 8 data bits, no parity, 1 stop bit and no flow control.
