• A telephone line connection can be established
to transfer data and files and effect downloads
• The smart battery can be recharged (the battery
can also be recharged through the terminal)
• You can perform back-to-back downloads by
connecting to another base station with a
docked terminal
Download To transfer files or data from a host
computer or sending terminal over a communication

Flash memory An area of non-volatile memory
where files can be stored. The Omni 3600 also has
a RAM-based file system. Files can be stored in
RAM (drive I:) or in flash (drive F:) memory area of
any file group (Groups 1–15).
Host computer Also called a download computer.
The primary or controlling computer in a multiple
computer operation. Also, a computer—usually a PC

Keyed file character set A limited set of 95
ASCII characters, from 00h to 5Fh (or 0 to 95 deci-

ate new records or modify existing records stored in
a keyed file such as CONFIG.SYS. See CON-
FIG.SYS file.
Keyed file record ASCII data, or variables, stored
in the terminal’s CONFIG.SYS file(s). A keyed file

Line cord A telephone-type cord with modular
plugs on each end to connect the base station to a

internal diagnostics are performed in system mode.
