.Dd March 1, 2008 .Dt UCOM 4 .Os .Sh NAME .Nm ucom .Nd USB tty support .Sh SYNOPSIS To compile this driver into the kernel, place the following line in your kernel configuration file: d -ragged -offset indent .Cd "device ucom" .Ed
p Alternatively, to load the driver as a module at boot time, place the following line in .Xr loader.conf 5 : d -literal -offset indent ucom_load="YES" .Ed .Sh DESCRIPTION The .Nm driver attaches to USB modems, serial ports, and other devices that need to look like a tty. 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.
p The .Va portno locater can be used to decide which port to use for devices that have multiple external ports. .Sh FILES l -tag -width ".Pa /dev/cuaU?" t Pa /dev/cuaU? t Pa /dev/ttyU? .El .Sh SEE ALSO .Xr tty 4 , .Xr uark 4 , .Xr uchcom 4 , .Xr uftdi 4 , .Xr umcs 4 , .Xr umct 4 , .Xr umodem 4 , .Xr uplcom 4 , .Xr usb 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 trhodes@FreeBSD.org in April 2002. .Sh BUGS Prior to .Fx 6.0 .Nm created
a /dev/ucom? rather than the uniform device names created today. Old scripts must be adjusted accordingly.
