These devices support most of the standard RS-232 features including baud rates ranging from 300 to 115200 bits per second. However, neither hardware nor software flow control seems to be supported. .Pp Access to devices under this driver is via the .Xr ucom 4 framework and device nodes. .Sh HARDWARE The .Nm driver supports the following adapters: .Pp .Bl -bullet -compact .It Belkin F5U109 .It Belkin F5U409 .It D-Link DU-H3SP USB BAY Hub .It Magic Control Technology USB-232 .It Sitecom USB-232 .El .Sh SEE ALSO .Xr tty 4 , .Xr ucom 4 , .Xr usb 4 .Sh HISTORY The .Nm driver appeared in .Fx 5.2 . It is loosely based on the .Xr ubsa 4 driver by .An Alexander Kabaev Aq Mt kan@FreeBSD.org with documentation from .An Wolfgang Grandeggar Aq Mt wolfgang@cec.ch . .Sh AUTHORS The .Nm driver was written by .An Scott Long Aq Mt scottl@FreeBSD.org .
