The debug uart is shared with slot 7, so in order to use sim slot 7 the
pin config and the uart config needs to be changed. Going back to using
the debug uart works by defining ENABLE_DBG_UART7

using the synchronous HAL library causes RX overflow after 5 bytes
on bulk incoming data (e.g. pasted).
this mainly due to printing synchronously the character, but to
further prevent congestion we switch to asynchronous (e.g.
interrupt driven) communication.
The RX part works great now (no overflow), but the TX part is
malfunctioning because the HAL Async library does not buffer the
data to be transmitted and expects it to be in memory until
the transmission is complete (which printf does not do).
This change will not be reflected in Atmel START since it does not
allow to set the underlying STDIO redirect peripheral to async.
