USLCOM(4)              FreeBSD Kernel Interfaces Manual              USLCOM(4)

NAME
     uslcom - Silicon Laboratories CP2101/CP2102/CP2103/CP2104/CP2105 based
     USB serial adapter

SYNOPSIS
     To compile this driver into the kernel, place the following lines in your
     kernel configuration file:

           device usb
           device ucom
           device uslcom

     Alternatively, to load the driver as a module at boot time, place the
     following line in loader.conf(5):

           uslcom_load="YES"

DESCRIPTION
     The uslcom driver supports Silicon Laboratories
     CP2101/CP2102/CP2103/CP2104/CP2105 based USB serial adapters.

     The datasheets for the CP2101/CP2102/CP2103 list the maximum supported
     baud rate as 921,600.  Empirical testing has shown that the rates
     1,228,800 and 1,843,200 also work, at least on some hardware, so the
     driver allows setting those rates.
