| 42 | .Os |
| 43 | .Sh NAME |
| 44 | .Nm uftdi |
| 45 | .Nd USB support for serial devices based on the FTDI chips |
| 46 | .Sh SYNOPSIS |
| 47 | To compile this driver into the kernel, |
| 48 | place the following lines in your |
| 49 | kernel configuration file: |
| 50 | .Bd -ragged -offset indent |
| 51 | .Cd "device uftdi" |
| 52 | .Cd "device ucom" |
| 53 | .Ed |
| 54 | .Pp |
| 55 | Alternatively, to load the driver as a |
| 56 | module at boot time, place the following line in |
| 57 | .Xr loader.conf 5 : |
| 58 | .Bd -literal -offset indent |
| 59 | uftdi_load="YES" |
| 60 | .Ed |
| 61 | .Sh DESCRIPTION |
| 62 | The |
| 63 | .Nm |
| 64 | driver provides support for RS-232 (and possibly RS-485) virtual COM |
| 65 | port functionality in various FTDI chips: |
| 66 | .Pp |
| 67 | .Bl -dash -compact -offset indent |
| 68 | .It |
| 69 | FT8U100AX multi-function hub controller chip |
| 70 | .It |
| 71 | FT8U232AM USB UART chip |
| 72 | .It |
| 73 | FT232 series USB UART chips |
| 74 | .It |
| 75 | FT2232 series dual USB UART/FIFO chips |
| 76 | .El |
| 77 | .Pp |
| 78 | The |
| 79 | .Nm |
| 80 | driver doesn't support any other serial protocol supported by these chips. |
| 81 | These protocols might be supported by libftdi userspace library. |
| 82 | .Pp |
| 83 | The device is accessed through the |
| 84 | .Xr ucom 4 |
| 85 | driver which makes it behave like a |
| 86 | .Xr tty 4 . |
