ucom(4) hang up

[KIYOHARA Takashi <kiyohara%kk.iij4u.or.jp@localhost>]

Hi! all,


My ucom(4) devices (ucom@uftdi x2) hangs up when tip(1) is executed.
After this change, it is happened.

  
http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/dev/usb/ucom.c.diff?r1=1.81&r2=1.82&only_with_tag=MAIN&f=h

Can we this problem be fixed?

Thanks,
