+# This ASCII line-based script is an EEPROM patch specification file for
+# cp2102-patch-ee-image.  The present EEPROM patch file is a demonstration
+# of what our tools can do: it replicates the same modifications to the
+# CP2102 EEPROM that were done by Foxconn in the making of their legendary
+# Pirelli DP-L10 phone.
+#
+# Needless to say, we (FreeCalypso) do NOT recommend patching the EEPROM
+# on some random CP2102 device or cable and turning it into a USB device
+# that pretends to be a Pirelli DP-L10.  The present EEPROM patch file is
+# NOT the right way to convert your CP2102 adapter to GSM baud rates -
+# a different, more proper procedure will be provided for that purpose.
+# Instead the present EEPROM patch file is only a demo, and perhaps a
+# starting point to be used if anyone is going to make a new CP2102-based
+# custom device despite this chip being NRND.

+# remap baud rates for GSM
