Linux ACP Modem (Mwave) mini−HOWTO

1.6. Which Systems are Supported

This version of the ACP Modem driver supports the IBM Thinkpad" 600E, 600, and 770 that include on−board ACP modem hardware.

1.7. Features of the Modem

The ACP Modem provides the following features:

Standard asynchronous COM port interface (NS16550A UART compatible) operation

Bell−103/212A, CCITT−V.21/V.22,V.22bis protocols with data from 300 to 2400 bps

CCITT−V.32 protocols with data rates of 4800, 9600 uncoded, and 9600 bps Trellis coded (Optional)

CCITT−V.32bis protocols with data rates of 4800, 9600, 12000, and 14400 bps (optional)

ITU−T V.34 protocols with data rates from 2400 to 33600 bps.

56K capable modem

Hayes AT Command Set compatibility

DTMF and pulse dialing

Asynchronous error recovery protocol

Error correction via Microcom Network Protocol (MNP) classes 1−4

Error correction via the V.42 error correction standard

MNP class 5 for up to 2x data compression

V.42bis for up to 4x data compression

"Adaptive Rate Negotiation" which provides for "Fallback / Fallforward" as line quality deteriorates or improves

Your modem contains 56K technology. To take advantage of this technology, you must first make sure that your Internet Service Provider (ISP) supports a 56K modem protocol. Significantly higher modem connection speeds, up to 56kbps, require all−digital transmission connections from your ISP to the line card in the central office from which your phone line is connected. The actual connection rate may be limited by the quality of your telephone lines. Telephone line quality may vary from location to location. Current regulations limit maximum trasfer rates to 53K. While your modem contains 56K technology, typical maximum connection rates in the receive direction may be significantly less than 56K. Currently, 56K capability is for the receive direction only. The transmit direction uses V.34 technology.
