DATAMAN S4 MANUAL
<BI>Note:<MI> Both devices are only polled
simultaneously at the
command prompt. If S4 is in the middle of doing
something requested
by the RS232, the keypad is ignored, and vice
versa. No other method
makes sense. <D>
<$IFiles;Sending and receiving>S4 receives
commands through the serial
interface in an interactive way i.e. it expects you to
wait for the
resulting output. You normally expect computers
programs to work
like that and when entering commands and data
by hand it causes no
problem. However, in the rare circumstance that
you wish to send
S4 commands from a batch-file which does not
wait for results, you
must make sure that S4's RTS signal handshakes
with your computer
to prevent it sending commands faster than S4 can
action them.
When sending files, remember that most
computers cannot process data
as fast as S4 can. To be safe, send at a slow baud
rate or connect
the RTS handshake line. You can usually see a
bad transmission if
you inspect the file after receipt - some of the lines
will be short
and contain bad characters.
