Lines: 6 Here's an example of a question I had awhile back and could never find an answer to: can the IIGS serial port be used to support HDLC synchronous communications? I know the key chip used is designed to support HDLC communications, and I know that localtalk is a synchronous protocol, but if one can, and how one could access the necessary features of the chip I don't know. The GS reference manuals didn't seem to have enough information to answer this question when I looked.
