| Hi,     I have planned to implement HDLC by using the following 
standards; [1] ISO/IEC 3309:1991(E), "Information Technology - Telecommunications and information exchange            between 
systems -High-level data link control (HDLC) procedures - Frame structure", 
International             Organization 
For Standardization, Fourth edition 1991-06-01.    [2]   ISO/IEC 3309:1991/Amd.2:1992(E), "Information 
Technology - Telecommunications and                
information exchange between systems - High-level data link control (HDLC) 
procedures - Frame              structure - 
Amendment 2: Extended transparency options for start/stop transmission", 
International             Organization 
For Standardization, 1992-01-15.    [3]   ISO/IEC 4335:1991(E), "Information Technology 
- Telecommunications and information exchange             between 
systems - High-level data link control (HDLC) procedures - Elements 
of  procedures",             International 
Organization For Standardization, Fourth edition 1991-09-15.    Are these the correct documents to implement the HDLC 
protocol?    Is there any other documents? regards  ram. Ramkumar
