UHMODEM(4) | NetBSD Kernel Interfaces Manual | UHMODEM(4) |
When the device attached, it will attach multiple ucom devices. The former one is main com device to use communication with your network provider, and others are sub com devices to monitor the condition of data communication and/or network status. These com devices can be used simultaneously.
The device is accessed through the ucom(4) driver which makes it behave like a tty(4).
