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:

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)
