Mageia Linuxを実行していますが、2つのシリアルポートを持つPCIカードがあり、マザーボード（ASUS H81M-A）にはオンボードシリアルポートがありません。PCIカードはWCHによって製造されているようです。カードに付属しているLinuxドライバーをインストールしようとしましたが、システムでファイルに大量のエラーが見つかり、ドライバーのインストールを中止しました。私のカードはこんな感じで、CH3825SP @ 1107があります。
そこで、オンラインでヘルプを探し始め、次のことを行うための情報を見つけました。
私は走っlspci -vてこれを得た。のセクションSerial controllerは私のPCIシリアルカードだと思います。

そして、このコマンドsudo setserial /dev/ttyS0 uart 16550Aを実行ttyS0して、ポートをPCIカードに設定しました。ブログ記事（Serial-Port-Work-Linux and electronics FAQ）によると、オンラインで見つけたのですが、シリアルPCIカードを使用するために必要なことはこれだけです。ただし、機能しません。setserialコマンドを実行すると、私のプログラムはにアクセスできなくなりますttyS0。私が何をしているか、これを機能させる方法がわかりません。ヒントやヘルプは大歓迎です。
更新 PCIのdmesgは次のとおりです。長すぎる場合は申し訳ありません。:)
