DATAMAN S4 MANUAL
16 Computer Operation
usually at 64K, when the system transfers the
buffer contents to disk. 64K characters is not
64K bytes, because a HEX file contains two
ASCII characters for every data byte plus
addresses, checksums and other odds and
ends. In fact it is more like 26K bytes. For small
PROMS this is enough. It is possible to send
the whole 64K as 3 chunks, then patch it
together with a word-processor and take out
the two spurious End-of-File lines.
A much better solution is to use some kind
of COMMS or TERMINAL program.
Terminal Emulating Programs.
A TERMINAL sends the information you type
at the keyboard through the serial port. It
displays what comes back through serial port
on your screen. When S4 is connected to your
computer running a terminal program, it might
seem that what you type appears on your
screen: that is not so. What your see is what
S4 chooses to send you in response:
sometimes this is what you typed: sometimes it
is not. Terminal programs usually let you send
and receive files as well, with handshaking
properly implemented, and that is all that is
required for complete control of S4.
S4 DRIVER.
Dataman supplies free terminal software for
your PC for use with S4. S4DRIVER has online
help and will work at speeds up to 115200
