From: Keith Petersen <W8SDZ@SIMTEL20> From: Bill Johnston CD-SP <bjohnsto at wsmr70a> To: w8sdz Re: Synchronism Keith, Some years ago I saw a good explanation of how a teletype printer becomes synchronized if the signal is turned on in the middle of a character. That is, suppose you just happen to switch the signal on in the middle of a character, and the first bit it sees is a spacing data character. How does it finally figure out that what it saw wasn't a start bit, and get itself properly synchronized with the real start bit of subsequent characters? Do you recall such an article, or do you have a good description of the process yourself? Seems to me that I might even have included a description of it in one of my articles in RTTY Journal about 10 or 12 years ago, but I can't find it, and I can't recall my favorite description that I like to give to newcomers! Thanks -- Bill, N5KR
