LAPM End-to-End Error Control Protocol
with Optional Data Compression

Applications
End-to-end error control, with optional compression, for applications such as:
• Graphical front-ends for information services
• Custom client-server remote access programs
• Remote access to local area networks
• Bridges & Gateways

Written in C++ as part of a polymorphic HDLC framework, this driver implements LAPM and is designed to be very small, portable, and device executive independent. It is extremely efficient and configurable to enhance response time and/or throughput. Verisons are available for both asynchronous (using AFT) and synchronous transmission.

V.42 bis compression option†
Data compression is available with the driver. The compression module is CCITT V.42 bis compliant, offering up to a 4:1 compression ratio. Unlike other compression schemes, V.42 bis never expands data.

Reasonable source code license terms.
