That file is to +be sent as binary cards. +.sp +F_ is the same as B_ except a form feed is prepended to the file. +.sp +U_ specifies that the rest of the line +is a file name. +After the job has been transmitted, +the file is unlinked. +.sp +.in -3 +Any error encountered will cause the daemon to +drop the call, wait up to 20 minutes and start over. +This means that an improperly constructed +df__ file may cause the same job to be submitted +every 20 minutes. +.sp +While waiting, the +daemon checks to +see that the lock____ file still exists. +If the lock____ is gone, the +daemon will exit. +.sp +.ti 0 +FILES /dev/dn0, +/dev/dp0, +/usr/dpd/* +.sp +.ti 0 +SEE ALSO opr(I) +.sp +.ti 0 +DIAGNOSTICS -- +.sp +.ti 0 +BUGS -- |
