Regardless of what the other language is with which you might be
familiar, the process of reading characters from an RS232 device
into memory and writing them to disk will be much the same in
Ada.  You need a manual for the device to determine whether it
is able to answer inquiries regarding the characters on screen
(most are not).

So you want to send various control functions to the terminal,
and you do that using Ada IO capabilities as you would the
IO capabilities of the other languages you use.  Or perhaps
on some operating systems (like VMS) you might want to use
OS-specific calls to obtain larger buffers or asynchrouous
input from a single read, or read-with-prompt semantics.

The process of reading characters from a terminal screen
really has much more to do with the model of terminal
than with the programming language, so you might consider
a hardware-specific newsgroup.
