ucom0

[TSaplin Mikhail]

Hi all
I have freeBSD 5.4
When i connect my nokia 2280 with DKU-5 (prolific cheep) it attache to ucom:
ucom0: Prolific Technology Inc. USB-Serial Controller, rev 1.10/3.00, addr 3

But cu -l /dev/ucom0 do not allows me write anything

Now i reboot to windows connect to internet through cable (it resets it?)
Reboot back to the FreeBSD and cu -l /dev/ucom0 now allows to write AT 
commands

Is there another way to reset/initialize connection with my phone?
