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

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 behaviour 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 locator can be used to decide which port to use for device that have multiple external ports.

Hi All,
I have a device driver that uses UARTserial port to write/read to-from a device.
That device driver is working fine on FC3 machine( kernel version 2.6.12)...
Now I am switching to FC9 (kernel version 2.6.25.11-97).I have changed the interrupt flag SA_INTERRUPT to IRQF_DISABLED... (0 Replies)
