Download HS X.25 C Source Library 1.3.18

HS X.25 is a software library in C (supplied with full source code) which implements ITU-T recommendation X.25. (with included HsDL (Data Link) and HsSock (Winsock interface) for X.25 over IP applications (XOT))

HS X.25 is a software library in C (supplied with full source code) which implements ITU-T recommendation X.25 - Interface between Data Terminal Equipment (DTE) and Data Circuit-terminating Equipment (DCE) for terminals operating in the packet mode and connected to public data networks by dedicated circuit.

HS X.25 internally at a lower layer interfaces to HsDL library. HsDL library is Data Link layer abstraction. When HS X.25 is ported into environment with LAPB or LAPD as data link layer, only HsDL module needs to change.

HsDL links directly to HsSock module (also included in this package) - Winsock interface component that provides reliable TCP transport services similar to LAPB / LAPD / HDLC.

HsX25 as provided to customer may be used immediately in X.25 over TCP (XOT) solution or it may be used with traditional LAPB or LAPD in which case only HsDL will need to be modified.

Main Features: * DTE operation * DCE operation * Multiple layer 2 links * 4095 VCs per link * SVC supported * X.25 version: ITU-T (formerly CCITT) 10/96 * outgoing calls * incoming calls * max packet lenght 1024 * all X.25 timer and counters implemented * interrupt packets supported * Statistics * Trace Function *

HsX25 as provided to customer may be used immediately in X.25 over TCP (XOT) solution or it may be used with traditional LAPB or LAPD in which case only HsDL will need to be modified.
Whats new in version 1.3.18:

• Support for the use of TCP keepalives to detect broken (abruptly terminated) XOT sessions. This release adds TCP keepalive support to Linux version only
