* uart fixes and BW improvements * uart: read_char straightly use hw buffer * +attributes for functions called by ISR * uart: BW improvements read_char straightly use hw buffer (+ ~10%bw) read by block (+ ~190%bw) (instead of generic Stream::readBytes) attributes for functions called by ISR remove overrun message remove some ISR flags which were not honoured * fix merge * fix buffer overflow * serial stress test sketch * astyle * serial stress example: interactive keyboard, stop reading, overrun * serial device test: bandwidth & overrun * update + HardwareSerial::hasError() * interactive overrun in example * astyle * Test using @plerup's SoftwareSerial as submodule (tag 3.4.1) * update upstream ref (fix warning) * host mock uart/read(buf,size) * reset style changes in submodules before style diff * update build_boards_manager_package.sh for submodules * trigger CI (removing space) * cannot reproduce locally the CI issue, setting bash -x option to get live trace * remove previously added (in this PR) 'set -e' in package builder (passes local tests, not real CI) script-comment new recipe.hooks.core.prebuild.3 (along with already commented .1 and .2) moved CI package test to be first on the test list remove 'set -x', wish me luck
