.Dd November 20, 2011 .Dt UMCT 4 .Os .Sh NAME .Nm umct .Nd Magic Control Technology USB-RS232 converter driver .Sh SYNOPSIS To compile this driver into the kernel, place the following lines in your kernel configuration file: d -ragged -offset indent .Cd "device usb" .Cd "device ucom" .Cd "device umct" .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 umct_load="YES" .Ed .Sh DESCRIPTION The .Nm driver provides support for USB to RS-232 converters based on the Magic Control Technology USB-232 design. 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.
p 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:
