IP-Comm360 HDLC Driver


Features include:

  • An HDLC driver for TargetLAPBTM, Blunk Microsystems' ISO/IEC 7776 LAPB protocol stack. May also be used as a stand-alone HDLC frame driver or with other third party protocol stacks. Supports all three 68302 SCC channels.

  • Inherent multiprocessing reduces host processor load. Minimal code runs on the host processor. The HDLC frame driver runs on the IP-Comm302's 68302 and is downloaded by the host processor during initialization. The processors communicate via the IP-Comm302's shared memory using an interrupt-driven protocol in a manner transparent to the application.

  • Transmit and receive clocks for each channel are independently configured as either externally or internally generated. Each channel has a dedicated baud rate generator to provide internal clocks and a watchdog timer to detect failures in external clocks.

  • Supports both RS-232 and RS-422 configurations of the XM-302 Transition Module.

  • Line signal monitoring is independently configured for each channel. Supports control of the RTS and DTR (RS-232 mode only) output signals and monitoring of the CTS, DCD, and DSR (RS-232 mode only) input signals.

  • Maintains statistics on the number of alignment, CRC, length, and overrun errors and on the number of received ABORTs. Statistics values can be read or printed to stdout.

  • Shipped with two sample applications: one using TargetLAPB and another for stand-alone testing of the frame driver.

  • Tested on the VIPC860, VIPC360, and VIPC610 IndustryPack carriers from SBS Modular I/O and the MVME162 IndustryPack carrier from Motorola.

  • Integrated with TargetTools™/ColdFire, the IDE for embedded development from Blunk Microsystems with an integrated compiler and kernel-aware debugger, visual code editor, search and replace tool, BDM for board bring-up, and fast Ethernet download.

  • Royalty free. Includes full ANSI C source code, user's manual, and one year of technical support.
