The following reply was made to PR bin/57630; it has been noted by GNATS.

Support for using the control device automatically was broken in rev.1.8 of lptcontrol.c. Existence of the documented control device was broken in FreeBSD-5 as part of devfs lossage. The documented control device is "/dev/lpctlN" (see lptcontrol(8), but devfs creates "/dev/lptN.ctl". The lpt driver also has support for control bits in the minor number. (The control device is a special case of this -- it uses bit 0x80.) There are 6 control bits, giving a total of 64 possible devices per unit. devfs only creates 2 of these. Bruce
