Hayes OPTIMA modems have a number of capabilities that allow
them to service advanced business and data communications applications.
Leased line support, access security with encrypted passwords,
remote configuration and the capability to support FAX servers
all make OPTIMA the right choice for business applications.
OPTIMA is also one of the few modems available
today which supports Synchronous communications - indeed
OPTIMA not only
supports Synchronous but has a unique "Hayes AutoSync" capability
which allows synchronous communications through a standard
serial PC port without the use of special, expensive Synchronous
adapter devices in the PC.
Synchronous communications involves a
series of protocols that were originally developed to allow
remote devices to
communicate
with Host systems such as Mainframes and Midrange systems,
maintaining a constant timing e.g. synchronization between
the two at all times. IBM was the principal developer of
synchronous techniques such as BiSync and SDLC (synchronous
data link control)
and the protocols themselves are named after IBM terminal
families such as 5250 and 3270. Synchronous protocols include
interactive
(3270 or 5250) and batch file transfer (3770 or 3780).
When used in its basic synchronous mode,
OPTIMA functions as a synchronous modem supporting any of
these protocols
when
attached to a synchronous port. When used in Hayes AutoSync
mode, OPTIMA attaches to a standard serial port and operates
in conjunction with software solutions from our developers
who provide emulation applications for each of the above
protocols. These applications have been developed for
both DOS and Windows
PC environments.
The beauty of the Hayes OPTIMA is that
users can perform common Asynchronous tasks such as Email
and Internet
as well as Synchronous
functions as such as PC to host/mainframe communications
with the same modem, through the same communications
port with no
cable or configuration changes.
