The PC/HOST File Transfer and Terminal Emulator Program (FTTERM) provides
3270, DEC VT100, DEC VT220 and 3101 terminal emulators, along with 3270 and
ASCII file transfer capabilities. In addition, FTTERM Version 2.1 expands
its connectivity options to let an IBM Personal Computer or Personal
System/2 operate on an IBM Token-Ring Network or a Broadband IBM PC
Network local area network (LAN).
When operating on the LAN, it uses the Enhanced Bios Interface Programs and
communicates through the IBM Local Area Network Asynchronous Connection
Server Program (LANACS), to connect to ASCII Hosts, dial Information
Providers, and obtain the use of Protocol Converters to allow access to IBM
hosts. File transfer is supported to ASCII hosts or IBM Hosts. FTTERM
Version 2.1 also supports an asynchronous connection for IBM Professional
Office System (PROFS) (TM) Applications Support Feature (PASF) Version
2.2.2 (non-Token-Ring LAN configurations) and GDDM-PCLK 1.1 through the
FTHLLAPI (FTTERM High Level Language Application Program Interface)
facility.
The actual session management is controlled at the 3174 and not by
FTTERM.DFT emulators like Personal Communications/3270 control sessions
within the PC. In previous microcode levels, an ASCII display connected to
the Async Emulation Adapter (AEA) was able to have only two sessions,
although Coax-type CUT terminals were allowed up to 5 sessions. Microcode
level B2 has extended that support to ASCII displays and the AEA.
We have not found a similar application with these functions on the
Macintosh. Simware offers a multi-session 3270 terminal emulators and file
transfer over asynchronous lines, if used in conjunction with their host
software Sim3278 VM or VTAM. RELAY provides only file transfer over async
lines to a mainframe running RELAY Communications' RELAY/VM or RELAY/TSO.
MacBLAST software for IBM mainframe also transfers text or binary files via
async ports or protocol converters. DCA (formerly Avatar) MacMainFrame DX
provides only single-session terminal emulation and file transfer over
asynchronous lines.
