SCC Drivers

Features include:

• Supports TargetLAPB^TM, Blunk Microsystems' ISO/IEC 7776 compliant LAPB protocol stack. May also be used as a stand-alone HDLC frame driver or with other upper layer protocols.
  
  
• Interrupt driven and DMA driven to reduce overhead and maximize throughput.
  
  
• Baud rate and line signal monitoring are configurable at run-time. The transmit and receive clocks are independently configured as either externally or internally generated.
  
  
• Contains watchdog timer to detect external transmit clock failures. Detects if outbound packets take excessive time to complete transmission.
  
  
• Supports control of the RTS and DTR output signals and monitoring of the CTS, DCD, and DSR input signals.
  
  
• Supports one SCC channel at speeds up to 1.8 Mbps using a 16 MHz MC68302. Multiple copies of the driver can be used to support multiple channels.
  
  
• Configurable for either NRZ or NRZI data encoding.
  
  
• Statistics counters are maintained on the number of received ABORTs, CRC errors, overrun errors, short frames, long frames, and byte alignment errors. Statistics values can be read or printed to stdout.
  
  
• Includes two sample applications, one using TargetLAPB and another that operates stand-alone.
  
  
• Extensively tested with TargetLAPB.
  
  
• Available for TargetOS^TM, Blunk Microsystems' full-featured royalty-free RTOS.
  
  
• 100% ANSI C code developed and tested using compilers from Software Development Systems and Microtec Research Inc.
  
  
• Royalty free. Includes source code, manual, sample applications, and one year of technical support.
