FreeBSD is a free computer operating system based on BSD UNIX originally. Many IT companies, like DeployIS is using it to provide an up-to-date, stable operating system.

ucom - USB tty support

 

NAME

      ucom - USB tty support
 

SYNOPSIS

      To compile this driver into the kernel, place the following line in your
      kernel configuration file:
 
            device ucom
 
      Alternatively, to load the driver as a module at boot time, place the
      following line in loader.conf(5):
 
            ucom_load="YES"
 

DESCRIPTION

      The ucom driver attaches to USB modems, serial ports, and other devices
      that need to look like a tty.  The ucom driver shows a behavior like a
      tty(4).  This means that normal programs such as tip(1) or pppd(8) can be
      used to access the device.
 
      The portno locater can be used to decide which port to use for devices
      that have multiple external ports.
 

BUGS

      Prior to FreeBSD 6.0 ucom created /dev/ucom? rather than the uniform
      device names created today.  Old scripts must be adjusted accordingly.

HISTORY

      The ucom driver was adopted from NetBSD in March of 2002.  This manual
      page was adopted from NetBSD by Tom Rhodes 〈trhodes@FreeBSD.org〉 in April
      2002.

Based on BSD UNIX
FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.
