dkleveld(3X) dkbreak()
Transmits an URP level-D BREAK code on an open NIO
CommKit Host Interface device. The BREAK is scheduled for
transmission in a separate URP block after any data already
queued for the circuit.
dkleveld(3X) dkusb()
Sends a two-byte URP unsequenced data block on an open NIO
CommKit Host Interface device. The unsequenced data block is
scheduled for the next transmission opportunity.
dkleveld(3X) isdkleveld()
Tests whether the top message at the Stream head contains an URP
level-D control code message. See the isdkleveld example later in
this chapter.
dkleveld(3X) isdkeof()
Tests whether the top message at the Stream head contains an URP
level-D control code message with an EOF code as the first entry.
See the isdkeof example later in this chapter.
dkleveld(3X) isdkclosed()
Tests whether the circuit associated with the NIO CommKit Host
Interface device has been disconnected by the other end of the
circuit. See the isdkclosed example later in this chapter.
dkmgr(3X) dkmgr()
Establishes the address as a server on the AT&T Data Switch,
using any interface or channel.
dkmgr(3X) dknmgr()
Establishes the address as a server on the AT&T Data Switch,
using any channel on the specified interface.
dkmgr(3X) dknnmgr()
Establishes the address as a server on the AT&T Data Switch,
using the specified channel on the specified interface.
dkmgr(3X) dkmgrack()
Accepts the incoming call to the server.
dkmgr(3X) dkmgrnak()
Rejects the incoming call to the server.
dkmgr(3X) dkinit()
Specifies the URP initialization mode for the incoming call to the
server.
dkmgr(3X) dkcktcfg()
Specifies the URP window size for the incoming call to the server.
dkmgr(3X) dk_chk_idle()
Verifies that the specified interface and channel are idle and not in
use on the system.
dkmgr(3X) dk_reset_ckt()
Resets the specified interface and channel to the idle state.
