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. .Pp The .Va portno locater can be used to decide which port to use for devices that have multiple external ports. .Sh FILES .Bl -tag -width ".Pa /dev/cuaU?" .It Pa /dev/cuaU? .It 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 .Pa /dev/ucom? rather than the uniform device names created today. Old scripts must be adjusted accordingly.
