UCHCOM(4) BSD Kernel Interfaces Manual UCHCOM(4)NAME
uchcom -- WinChipHead CH341/CH340 serial adapter driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:
device uchcom
device ucom
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
uchcom_load="YES"
DESCRIPTION
The uchcom driver provides support for the WinChipHead CH341/CH340 USB-to-RS-232 Bridge chip.
The device is accessed through the ucom(4) driver which makes it behave like a tty(4).
HARDWARE
The uchcom driver supports the following adapters:
o HL USB-RS232
SEE ALSO tty(4), ucom(4), usb(4)HISTORY
The uchcom driver first appeared in NetBSD. The first FreeBSD release to include it was FreeBSD 8.0.
BUGS
Actually, this chip seems unable to drive other than 8 data bits and 1 stop bit line.

I'm a beginner to the Linux programming and trying my hands on some device driver examples while practising. The below code (a trimmed down version of tiny_tty.c from ldd3 book) loads perfectly using insmod and I'm able to see it in /proc/tty/drivers , /proc/modules and device nodes are getting... (1 Reply)
