Plug and Play

PnP ISA Specification 1.0a for one logical device, PnP

 

autoconfguration sequence compliant, full 16-bit address

 

decode to meet Microsoft’s PC 95 requirements for Windows

 

Logo certification.

Error Correction

ITU V.42 (LAP-M and MNP Classes 2–4)

Data Compression

ITU V.42bis (4:1 compression) and MNP 5 (2:1 compression)

Speed Detection

Automatic speed detection and switching between available

 

speeds

Fallback

In adverse line conditions, the modem falls back from its

 

current operating speed to the next reliable slower speed in

 

2400 bps decrements (V.34 mode). If conditions improve, the

 

modem falls forward to the fastest reliable speed in 2400 bps

 

increments. In V.90/K56flex mode, modem falls back and

 

falls forward in increments of 2000 bps

Modes of Operation

Full-duplex operation over dial-up lines, automatic dialing,

 

automatic or manual answer

Flow Control

Software (XON/XOFF), hardware (RTS/CTS)

Intelligent Features

Fully AT command compatible, autodial, redial, pulse or tone

 

dial, dial pauses, call status display, auto-parity and data rate

 

selection, keyboard-controlled modem options, nonvolatile

 

memory and on-screen displays for modem parameters
