LT Win Modem Chipset ID

With later driver versions, the response to the command
AT i5
includes the modem driver version as well as PCI ID information:

ati5
8.10,0,19,11C1,0442,141C,9300

The fifth field is the Device ID, and can be used to determine which chipset/DSP is on the modem, although some Mars3 boards may have been upgraded to Mars 3.2 without changing the PCI ID - see note at bottom of the chart:

Device IDChipset
0440Mars 2 data/fax/voice
0441Mars 2 data/fax only
0442Mars 2 data/fax/tam only
0448Mars 2 Global - data/fax/voice
0449Mars 2 Global - data/fax only
044AMars 2 Global - data/fax/tam
0444Apollo 2 data/fax only; Modem/LAN combo behind Intel 82559

0458Mars 3 Mercury - data/fax/tam only
0459Mars 3 Mercury - data/fax/tam only - Global
045AMars 3 Perseus - data/fax/tam only (North America & Global)
045BApollo 3 Perseus - data/fax only; Modem/LAN combo behind Intel 82559
045CApollo 3 Mercury - data/fax only; Modem/LAN combo behind Intel 82559
045DMars 3 Mercury - data/fax/tam only - Global for Cardbus modem product
044CMars 3.2 Mercury - data fax only when no eeprom is present (North America)

NOTE: If the device ID indicates Mars 3 or Apollo 3, the modem might actually use the 3.2 V.92 capable chipset. In this case, Windows will report &REV_02 at the end of Modem Information box from Control Panel -> Modems -> Modem Properties -> Diagnostics (later versions of Windows only; for earlier versions of Windows, this information is in the Registry and can be viewed with Regedit. In Windows XP: Control Panel -> Phone & Modem Options -> Modems Tab -> Properties -> Diagnostics Tab: scroll the Modem Information value display so you can see the end of the value as shown below: (here, device ID 442 & REV_01)

Key: Mars = PCI; Apollo = ISA
Perseus - Solid-state DAA
Mercury - electro-mechanical DAA

Mars 3.2 = 1648C DSP (V.92-capable with all 8.xx driver versions)
