I guess it will be necessary to remove a sysctl oid from a parent sysctl tree before destroying ucom structures. It's would be better to do in ucom_detach() but now there is no a pointer to a parent device structure from there. Now all drivers that use ucom pass a pointer to parent softc structure to ucom_attach(). Is there any reason for this? May be it's would be more useful to pass a pointer to a parent device structure. > Can you explain a bit more how you use this information in your scripts? I've got a gps receiver and a mobile phone that supported by the umodem driver. I can attach its in any order. So I use sysctl to generate gpsd and ppp configs with appropriate values of serial port. -- Mykhaylo Yehorov
