Softbank Airターミナル3 (B610s-77a)のブートメッセージをシリアルコンソールで見てみる

とあるリサイクルショップで、Softbank Airターミナル3を100円で買って来た。 Huawei Technologies Co., Ltd.製で、型番はB610s-77aと裏面に書いてある。

はるろいどの冒険日記 SoftBank Air ターミナル3で遊ぶ(準備編)によると、 底面のSIMカードスロットの隣にあるUSB micro B端子にUARTの端子が出ているらしい。

USB端子の接点	UART
GND	GND
D+	RXD
D-	TXD

と言うことで、micro BとUSB Type-Cを両端に持ったUSBケーブルを底面のUSB micro B端子に差し込み、 秋月電子のUSBtype-CコネクターDIP化キット(全ピン版)にUSB Type-C側の端子を接続した。 更に、USBtype-CコネクターDIP化キット(全ピン版)の10番のD-ピンはTXDなので、 秋月電子のFTDI USBシリアル変換ケーブル(3.3V)の黄色の線のRXDに接続し、 9番のD+ピンはRXDなので橙色の線のTXDに、 8番のGNDピンはUARTでもGNDなので黒色のGNDに接続した。

FTDI USBシリアル変換ケーブル(3.3V)のUSB A端子をNetBSDマシンに接続して、ucom1として認識された。 以下のように実行して、115200 bpsで接続すれば、ブートメッセージを見ることができた。
