Texas Instruments has just released (2 months ago) information on the
TMS9542 (TMS99533), "a 1200 BPS, single-chip, phase-shift-keyed modem
compatible with the Bell 212A, CCITT V.22, and Racal-Vadic 3400
specifications.  All of the options, alternatives, and modes of
operation supported by these modems are included."

Features:

Bell 212A compatible
CCITT V.22 compatible
Racal-Vadic 3400 compatible
Originate/Answer modes
Simplex, half duplex, and full duplex capabilities
Sychronous/Asynchronous modes
Variable character length (8-11bits) in asynchronous mode
Analog loop back test mode
On-chip diagnostic and self-test mode
TTL-compatible digital serial interface
Switched-capacitor with N-channel double-poly silicon-gate MOS technology
28-pin dual in-line (DIP) package

These are preliminary specs (11/30/83) and cannot be guaranteed by
anybody, especially myself.  Why, even TI isn't quite sure what to call
it (99532, 99533, 9542).
