Subject: [sisyphus] при обращении к /dev/ttyLT0 виснет комп
Date: Mon, 23 Jan 2006 09:43:41 +0300
Message-ID: <43D47B1D.7030405@mail.ru> (raw)

Приветствую всех!
Установил в комп winmodem с целью удаленного управления (com порт
единственный и занят UPS кабелем). Установил через apt-get
kernel-modules-ltmodem. При попытке обращения к устройству
/dev/ttyLT0 любым средством (minicom, cat) и под любым
пользователем компьютер зависает намертво лечится только через
аппаратный RESET. Естественно, что такие сбросы не проходят
бесследно для файловвой системы. Это же модем под FreeBSD, правда
в другой машине работает нормально. Как можно порешать эту
проблему? Ниже вывод всеческих информационных команд.
