Introduction
Asynchronous Serial Communications
Telnet/iX
Telnet/iX provides the Telnet service over Transmission Control
Protocol/Internet Protocol (TCP/IP) on MPE/iX. The Telnet/iX Client
enables users on an HP 3000 to have direct access to HP 9000, HP 3000,
and non-HP systems that support Telnet and TCP/IP. The Telnet/iX
Server enables users on a remote system running standard Telnet
services to logon and run most applications on the HP 3000. Many
MPE/iX file system intrinsics are supported over Telnet/iX Server
connections. Please see the chapter “Programming for PAD, DTC
Telnet, Telnet/iX Server and VT Devices” in this manual for more
details.
DTC Telnet
A DTC with a Telnet Access Card (TAC) provides Telnet access to an
MPE/iX system. Only one TAC is needed per network. The terminal
data is transmitted to the Telnet Access Card in the DTC. The DTC
then transmits the data to the MPE/iX system. For the purposes of
asynchronous serial communications, the terminals connected through
DTC Telnet are non-nailed devices with special control restrictions.
Those restrictions are noted in this manual where appropriate.
Otherwise, DTC Telnet is transparent to your program.
