Hi,
I found this:
http://www.smecc.org/sage_a_n_fsq-7.htm at photo 22 it claims:
22. Simplex.jpg. This console provided operation and maintenance of the Long
Range Inputs and Outputs. Simplex because there was no redundant hardware.
Each radar station fed digitized data to the DC over public telephone lines (a
first - they had to invent the modem!). The DC also sent data to the
neighboring DCs and to the Command Center (the AN-FSQ-8 computer).
but...does anyone know the first data of a binary
(not ASCII)
file transmission via modem?
I assume that was a typo, and you want the date, not the data?
(I know of some done in 1975, from an IBM
mainframe to a DG Nova.)
At least as early as 1965 IBM sold equipment that could do this, so
I rather imagine people probably did binary transfers even in those days,
but I don't have any proof of it.
