Host Connectivity
Hand Held Products offers several host connectivity options for Dolphin 7200 RF
wireless LAN solutions. Direct Connect TN Client software is a thick-client solution
that connects Dolphin 7200 RF ™ computers directly to host applications via TN3270,
TN5250 or TNVT terminal emulation using industry-standard TCP/IP protocol.
Another option is a three-tier client server solution, or thin-client implementation, for
3270, 5250 and VT100/220 terminal emulation that uses a Universal Gateway. The
Gateway establishes communication to a host such as an AS400 and maintains
communication to both the Dolphin 7200 RF terminal and the host.
Thick-Client Terminal Emulation
PowerNet TN Client (telnet client) software allows the Dolphin 7200 RF terminal to
communicate directly with applications running on AS/400, ES/9000, HP/6000 or
other hosts connected to an Ethernet backbone and that support TCP/IP. The
TNVT, TN3270, and TN5250 emulations use TCP/IP to communicate from the
Dolphin 7200 RF™ terminal through the access point to the host. There is no
network controller or server.
