Создать порт позволяет (./mxaddsvr), но в /usr/lib/npreal2/driver/npreal2d.log идёт ошибка - Master tty open fail (/proc/npreal/0)!
Создавать скрипт запуска (https://www.moxa.com/en/support/product-support/product-faq/when-i-install-the-nport-real-tty-driver-on-debian-i-see-error-message)
пробовал, безрезультатно. При этом ping идёт и через telnet доступ есть.
Данный драйвер устанавливал не впервые, до этого таких проблем не было.
Прошу подсказать возможные пути решения.
