ucom(4) USB tty support


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.conf5:



The driver attaches to USB modems, serial ports, and other devices that need to look like a tty. The driver shows a behavior like a tty(4). This means that normal programs such as tip(1) or ppp(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.




The driver was adopted from Nx in March of 2002. This manual page was adopted from Nx by An Tom Rhodes Aq [email protected] in April 2002.


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