+# sredird V2.2.1
+# - http://www.ibiblio.org/pub/Linux/system/serial/   sredird-2.2.2.tar.gz
+# - does not acknowledge SET_CONTROL (RTS/DTR) correctly, always responding
+#   [105 1] instead of the actual value.
+# - SET_BAUDRATE answer contains 4 extra null bytes -> probably for larger
+#   numbers than 2**32?
+# - To get the signature [COM_PORT_OPTION 0] has to be sent.
+# - run a server: while true; do nc -l -p 7000 -c "sredird debug /dev/ttyUSB0 /var/lock/sredir"; done
+#=============================================================================
+# telnetcpcd (untested)
+# - http://ftp.wayne.edu/kermit/sredird/telnetcpcd-1.09.tar.gz
+# - To get the signature [COM_PORT_OPTION] w/o data has to be sent.
+#=============================================================================
+# ser2net
+# - does not negotiate BINARY or COM_PORT_OPTION for his side but at least
+#   acknowledges that the client activates these options
+# - The configuration may be that the server prints a banner. As this client
+#   implementation does a flushInput on connect, this banner is hidden from
+#   the user application.
+# - NOTIFY_MODEMSTATE: the poll interval of the server seems to be one
+#   second.
+# - To get the signature [COM_PORT_OPTION 0] has to be sent.
+# - run a server: run ser2net daemon, in /etc/ser2net.conf:
+#     2000:telnet:0:/dev/ttyS0:9600 remctl banner
