synchronous transmission

By eddie ·
I need to know for a college homework assignment what these acronyms stand for. They are all components of a synchronous transmission data packet or frame.
SYN
SOH
STX
ETX
EOT

Anyone that could help, it would be deeply appreciated.

character definitions

by shiny_topadm In reply to synchronous transmission

Hi, what you have is a short list of named ASCII characters that are used in all kinds of data comm., including synchronous. They are usually defined as follows:

name definition value(base 10)

SYN Synchronization Character char(22)
SOH Start of Header char(1)
STX Start of Text char(2)
ETX End of Text char(3)
EOT End of Transmission char(4)

Those listed are a subset of "non-printing" ASCII characters that are used to control some communication device, and are sent before and after (as needed) the actual data bytes. hope this helps, -Will
