+pySerial
+--------
+This module capsulates the access for the serial port. It provides backends
+for stadard Python running on Windows, Linux, BSD (possibly any POSIX
+compilant system) and Jython. The module named "serial" automaticaly selects
+the appropriate backed.
+
+It is released under a free software license, see LICENSE.txt for more
+details.
+
+(C) 2001-2002 Chris Liechti <cliechti@gmx.net>
+
+
+Features
+--------
+- same class based interface on all supported platforms
+- port numbering starts at zero, no need to know the port name in the user
+  program
+- port string can be specified if access through numbering is inappropriate
+- support for diffrent bytesizes, stopbits, parity and flow control
+  with RTS/CTS and/or xon/xoff
+- working with or without receive timeout
+- file like API with "read" and "write"
+- The files in this package are 100% pure Python.
+  They depend on non standard but common packages on Windows (win32all) and
+  Jython (JavaComm). POSIX (Linux, BSD) uses only modules from the standard
+  python distribution)
+- The port is set up for binary transmission. No NULL byte stripping, CR-LF
+  translation etc. (which are many times enabled for POSIX.) This makes this
+  module universally useful.
+
+
+Requirements
+------------
+- Python 2.0 or newer (1.5.2 untested)
+- win32all extensions on Windows
+- "Java Communications" (JavaComm) extension for Java/Jython
+
+
+Installation
+------------
+Extract files from the archive, open a shell/console in that directory and
+let Disutils do the rest: "python setup.py install"
+
+The files get installed in the "Lib/site-packages" directory in newer
+Python versions.
+
+
+Short introduction
+------------------
+import serial
+#open port 0 at 9600,8,N,1, no timeout
+ser = serial.Serial(0)
+ser.write("hello")  #write a string
+ser.close()
+
+#open port at 19200,8,N,1, 1s timeout
+ser = serial.Serial('/dev/ttyS1', 19200, timeout=1)
+x = ser.read()      #read one byte
+s = ser.read(10)    #read up to ten bytes (timeout)
+ser.close()
+
+Parameters for the Serial class
+-------------------------------
+ser = serial.Serial(
+    port,                   #number of device, numbering starts at
+                            #zero. if everything fails, the user
+                            #can specify a device string, note
+                            #that this isn't portable anymore
+    baudrate=9600,          #baudrate
+    bytesize=EIGHTBITS,     #number of databits
+    parity=PARITY_NONE,     #enable parity checking
+    stopbits=STOPBITS_ONE,  #number of stopbits
+    timeout=None,           #set a timeout value, None for waiting forever
+    xonxoff=0,              #enable software flow control
+    rtscts=0,               #enable RTS/CTS flow control
+)
+
+Constants
+---------
+parity:
+    serial.PARITY_NONE
+    serial.PARITY_EVEN
+    serial.PARITY_ODD
+stopbits:
+    serial.STOPBITS_ONE
