-/*
- * TA test
- *
- *  Updated for New TA Baseboard (rev Aug-Nov 2015.)
- *
- *  TODO maybe have a mode where the serial port I/O can be swapped,
- *   such that what the nRF generates is sent out the serial port,
- *   and what comes in the serial port goes into the nRF.
- *   Maybe could use the now-unused CTS pin for that.
- *
- *   Using
- *     rev 327 of BLE_API  
- *     rev 102 of nRF51822   w/ modification--See below
- *     rev  97 of mbed lib
- *       corresponding to:
- *         rev 493 of mbed-src   w/ modification to targets/hal/TARGET_NORDIC/TARGET_MCU_NRF51822/serial_api.c
- *                                so things compile properly.*
- *        * Now using $Sub$$UART0_IRQHandler to override UART0_IRQHandler without needing to use lib source.
- *
- *    *** Now using mbed-src again to modify startup code to use full 32k RAM on QFAC part        20160104  ALS
- *         while still using RBL BLE Nano as a target:
- *           Copied files  nRF51822.sct  and  startup_nRF51822.s
- *             from  targets/cmsis/TARGET_NORDIC/TARGET_MCU_NRF51822/TOOLCHAIN_ARM_STD/TARGET_MCU_NORDIC_32K
- *             to    targets/cmsis/TARGET_NORDIC/TARGET_MCU_NRF51822/TOOLCHAIN_ARM_STD/TARGET_MCU_NORDIC_16K
- *             (Stomping the 16k settings w/ 32k settings.)
- *
- *   Changed
- *     nRF51822/nordic/pstorage_platform.h  PSTORAGE_MIN_BLOCK_SIZE  changed from 0x010 to 4.

-// Note:  From the datasheet:
-//  PSELRXD, PSELRTS, PSELTRTS and PSELTXD must only be configured when the UART is disabled.
-// But a version of serial_init() erroneously enabled the uart before the setting of those,
-//  which messed up flow control.  Apparently the setting is ONCE per ON mode.  ARGH!
-//  So we made our own versions of Serial and SerialBase (MySerial and MySerialBase)
-//  to not use serial_init() in serial_api.c, so flow control is setup correctly *
-//  MTSSerial now uses our MySerial instead of Serial, and now uses hw flow control by default *
-//  [* We can't change the uart interrupt vector, so we comment-out the handler in
-//     serial_api.c, and rebuild the mbed lib for low-level hw flow control to work.] - No need now.
-//  * Now using $Sub$$UART0_IRQHandler to override UART0_IRQHandler without needing to use lib source.
-//    NVIC_SetVector( UART0_IRQn, (uint32_t)My_UART0_IRQHandler );  // Might have worked--No need.

-//  internal buffer--Rx servicing usually is fast enough not to need hw flow control, so it's okay.
