COMMUNICATIONS SOFTWARE
Because software directs the computer and modem to communicate
with each other, you will need Mirror III (available from Motorola) or
another communications software package for most data mode opera-
tions involving the modem. After installing the modem consult the soft-
ware user's manual for information on the communications software,
commands, and features. Software operating commands provide the
operator with complete control of the modem.
For operation as a fax modem, a computer and a Class 1 fax software
package are required. A fax connection cannot be established except
with software control. You will need FaxTalk Plus (available from
Motorola) or another Fax communication package.
DESCRIPTION
Functional
The V.3400 processes serial asynchronous data from a DTE at all stan-
dard rates from 300 bps to 115.2 kbps, and serial synchronous data at
rates from 300 to 28.8 kbps. Transmission can be over either dial-up
lines or either 2- or 4-wire leased lines. The maximum line speed is
28.8 kbps. Built-in test features can determine system performance and
isolate faults in the data link.Operation and configuration are controlled
by either the front panel LCD, the AT command set, or the V.25 bis
command set.
