The .Nm driver shows a behavior like a .Xr tty 4 . This means that normal programs such as .Xr tip 1 or .Xr ppp 8 can be used to access the device. .Sh SYSCTL VARIABLES The following variables are available as both .Xr sysctl 8 variables and .Xr loader 8 tunables: .Bl -tag -width indent .It Va hw.usb.ucom.debug Debug output level, where 0 is debugging disabled and larger values increase debug message verbosity. Default is 0. +.It Va hw.usb.ucom.device_mode_console +When set to 1, the +.Nm +driver will mark terminals as console devices when operating in device mode. +Default is 1. .It Va hw.usb.ucom.pps_mode Enables and configure PPS capture mode as described below. .Sh Pulse Per Second (PPS) Timing Interface The .Nm driver can capture PPS timing information as defined in RFC 2783. The API, accessed via .Xr ioctl 2 , is available on the tty device. To use the PPS capture feature with .Xr ntpd 8 , symlink the tty device to .Va /dev/pps0. .Pp The .Va hw.usb.ucom.pps_mode sysctl configures the PPS capture mode. It can be set in .Xr loader.conf 5 or .Xr sysctl.conf 5 . The following capture modes are available: .Bl -tag -compact -offset "mmmm" -width "mmmm" .It 0 Capture disabled (default). .It 1 Capture pulses on the CTS line. .It 2 Capture pulses on the DCD line. .El .Sh FILES .Bl -tag -width "/dev/ttyU*.init" -compact .It Pa /dev/ttyU* for callin ports .It Pa /dev/ttyU*.init .It Pa /dev/ttyU*.lock corresponding callin initial-state and lock-state devices .Pp .It Pa /dev/cuaU* for callout ports .It Pa /dev/cuaU*.init .It Pa /dev/cuaU*.lock corresponding callout initial-state and lock-state devices .El .Sh SEE ALSO .Xr tty 4 , .Xr uark 4 , .Xr ubsa 4 , .Xr ubser 4 , .Xr uchcom 4 , .Xr ucycom 4 , .Xr ufoma 4 , .Xr uftdi 4 , .Xr uhso 4 , .\".Xr ugensa 4 , .Xr uipaq 4 , .Xr umcs 4 , .Xr umct 4 , .Xr umodem 4 , .Xr umoscom 4 , .Xr uplcom 4 , .Xr usb 4 , .Xr uslcom 4 , .Xr uvisor 4 , .Xr uvscom 4 .Sh HISTORY The .Nm driver was adopted from .Nx in March of 2002. This manual page was adopted from .Nx by .An Tom Rhodes Aq Mt trhodes@FreeBSD.org in April 2002. .Sh BUGS Prior to .Fx 6.0 .Nm created .Pa /dev/ucom? rather than the uniform device names created today. Old scripts must be adjusted accordingly.
