the DTC/X.25 Network Access (residing on the
Datacommunications and Terminal Controller and
configured at the OpenView Windows Workstation).
Together, these two components provide a network
connection on HP e3000 systems to private and
public X.25 packet-switched networks (PSNs).
X.29 The protocol that defines the interface for data
exchange between a packet-mode DTE and a remote
Packet Assembly/ Disassembly (PAD) facility over a
packet-switching network.
XON/XOFF protocol The flow control used by
MPE/iX systems to protect against data overruns.
XON/XOFF protocol is controlled by the data
recipient who sends an XOFF character (ASCII
DC3) to the sender if it is unable to continue to
receive data. The sender suspends transmission
until it receives an XON character (ASCII DC1).
X.Series (X.##) CCITT recommendations A set
of recommendations for data communication
networks governing their services, facilities, and
terminal equipment operation and interfaces.
