.Dd November 20, 2011 .Dt UCHCOM 4 .Os .Sh NAME .Nm uchcom .Nd WinChipHead CH341/CH340 serial adapter 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 uchcom" .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 uchcom_load="YES" .Ed .Sh DESCRIPTION The .Nm driver provides support for the WinChipHead CH341/CH340 USB-to-RS-232 Bridge chip.
p The device is accessed through the .Xr ucom 4 driver which makes it behave like a .Xr tty 4 . .Sh HARDWARE The .Nm driver supports the following adapters:
p l -bullet -compact t HL USB-RS232 .El .Sh SEE ALSO .Xr tty 4 , .Xr ucom 4 , .Xr usb 4 .Sh HISTORY The .Nm driver first appeared in .Nx . The first .Fx release to include it was .Fx 8.0 . .Sh BUGS Actually, this chip seems unable to drive other than 8 data bits and 1 stop bit line.
