Here's the scoop (some details omitted because I don't want to write
a novel, and you didn't ask for them):

TrailBlazer Plus ----------------------
Modulations: PEP (19200), V.22bis (2400), Bell 212/V.22 (1200), Bell 103 (300).
RS232 Interface speeds: 19200, 9600, 4800, 2400, 1200, 300, Autobaud.
Protocols (error correction): MNP4, V.42 (PEP is also error corrected).
Data Compression: MNP5, V.42bis (PEP has LZW-style compression also).
Protocols (file transfer): X/Ymodem, Kermit, Uucp.

T2000----------------------------------
Same as TB+ above, but includes support for IBM SDLC synchronous links
at 19200 bps.  (actually, the SDLC mode has been given to the TB+ and
the T2000 will eventually be phased out)

T1000----------------------------------
Same as TB+ above, except PEP mode is 9600 bps instead of 19200, and
V.42/V.42bis is not supported.

T2500----------------------------------
(the 'kitchen sink' modem)  Same as TB+ above, but adds the
T2000's IBM SDLC mode, and the V.32 modulation.
File transfer protocol support is available in V.32/MNP mode 
as well as PEP.

T1500----------------------------------
A T2500 modem without PEP modes.  Will eventually be replaced by 
the T1600.

T1600----------------------------------
Modulations: V.32, V.22bis, Bell 212/V.22, Bell 103/V.21, (no PEP).
RS232 Interface Speeds: 38400, 19200, 14400, 12000, 9600, 7200, 4800,
2400, 1200, 300, Autobaud.
All other features same as TB+ above, except file transfer protocol
support is available in V.32/MNP mode.
