Computer devices {adapter} can make bits into line characters.
Computer devices {data communications controller} {datacom} can control data input and output from different terminals.
types
Datacoms {uniplexor} {single line control} (SLC) can take bits from one line and pass characters to CPU. Datacoms {multiplexor} {multi-line control} (MLC) can take bits from many lines, sort bits by logic, and send characters to CPU. Datacoms {front-end processor} (FEP) can take bits from several lines, assemble them into words, and send words to CPU. Datacoms {data communications processor} can take bits from one line, assemble them into words, add message header, queue messages, and send them to memory or input-output processor.
Devices {modem}| {data set} can convert digital bits to analog data, or vice versa, or alter line bit streams.
Devices {sort-merge} can manipulate input and output forms.
