-; This disassembly is a quick look at the firmware that has been read out
-; of a Huawei GTM900-B modem module.  Unlike most other phone and modem
-; vendors' firmwares, this fw exhibits very few changes relative to TI's
-; reference version.  Here I have only dug far enough to get to the
-; init module with the Init_Target() function and the ARMIO module with
-; the GPIO setup.

+; This disassembly is a quick look at the firmware that has been read out
+; of a Huawei GTM900-B modem module.  Unlike most other phone and modem
+; vendors' firmwares, this fw exhibits very few changes relative to TI's
+; reference version.  Here I have only dug far enough to get to the
+; init module with the Init_Target() function and the ARMIO module with
+; the GPIO setup.
