uplcom(4) does not work on cuaU0 ?

Hello,

Here, if uplcom is attached to cuaU0, the serial connection does not
work, as far i can see it does not send anything :

kernel: uplcom_pre_param: 
kernel: uplcom_cfg_param: sc = 0xc7416200
kernel: uplcom_cfg_param: rate=9600 fmt=0 parity=0 bits=8
kernel: uplcom_pre_param: 
kernel: uplcom_cfg_set_dtr: onoff = 1
kernel: uplcom_cfg_set_rts: onoff = 1
kernel: uplcom_cfg_param: sc = 0xc7416200
kernel: uplcom_cfg_param: rate=57600 fmt=0 parity=0 bits=8

that's all

But if attached to cuaU3, it works fine. The difference is the use
of an u3g key using cuaU0.

kernel: ugen0.3: <Prolific Technology Inc.> at usbus0
kernel: uplcom0: <Prolific Technology Inc. USB-Serial Controller D,
class 0/0, rev 1.10/3.00, addr 3> on usbus0

kernel: uplcom_cfg_set_rts: onoff = 1
kernel: uplcom_cfg_set_dtr: onoff = 1
kernel: uplcom_cfg_set_rts: onoff = 1
kernel: uplcom_write_callback: actlen = 1
kernel: uplcom_write_callback: actlen = 1
kernel: uplcom_write_callback: actlen = 32
...

Any clue?

Thanks, regards.
