They are 2- or 4-port adapters with full-featured +16550-compatible UARTs and very flexible baud generators. Also, these chips +support RS422/RS485 and IrDA oprations. +.Pp +The device is accessed through the +.Xr ucom 4 +driver which makes it behave like a +.Xr tty 4 . +.Pp +Different ports on device are presented as sub-units, like +.Pa /dev/ttyU0.1 +and +.Pa /dev/ttyU0.2 +.Sh HARDWARE +The +.Nm +driver was tested on the following adapters: +.Pp +.Bl -bullet -compact +.It +ST Lab U-360 two-port serial USB adapter +.It +ST Lab U-400 four-port serial USB adapter +.El +.Sh SEE ALSO +.Xr tty 4 , +.Xr ucom 4 , +.Xr usb 4 +.Sh BUGS +This driver doesn't support access to any fine tunes of +chip, like RS522/RS485 mode, non-standard baudrates, etc. +.Sh HISTORY +The +.Nm +driver +appeared in ports since December of 2010. +.Sh AUTHORS +.An -nosplit +The +.Nm +driver was written by +.An Lev Serebryakov +.Aq lev@FreeBSD.org . |
