Chapter 6 RAPID!
Commands
182 WCDMA Options Version 6.20
xonoff= defines whether the software handshake will
be used. A ‘0’ switches the software handshake off, while
‘1’ turns it on. Software handshake means that the
receiver (RAPID! program) may halt the transmission by
sending ASCII 19 (Ctrl-S) to the transmitter. A Ctrl-Q
(ASCII 17) sent to the transmitter will continue transmis-
sion again. Default value is ‘0’ (no software handshake).
rts= defines whether the hardware handshake will be
used. A ‘0’ switches the hardware handshake off, while ‘1’
turns it on. Hardware handshake means that the receiver
(RAPID! program) will only allow the transmitter to send
while it is expecting data in an
INPUT command. Physi-
cally, pin RTS will be kept to ‘low’ and only turn to ‘high’
when the RAPID! program expects input data. Default
value is ‘0’ (no hardware handshake).
cts= states, whether the signal on pin CTS will be
ignored (value = ‘1’) or listend to (value = ‘0’). If
cts=0,
the transmitter is only allowed to send data as long as
the signal on pin CTS is active (i.e. ‘high’). In case CTS is
to be ignored
cts=1, the receiver (RAPID! program) will
always wait until all characters have been transmitted
(please see parameter
wait=). Default value is ‘0’ (CTS
signal will be followed).
time= with the help of this parameter, you may set a
timeout in seconds. When the timeout expires, an empty
string will be delivered to the RAPID! program as input.
Default is 600 seconds (5 minutes).
end= specifies the end byte (usually ASCII 10 or ASCII
13). The valid range is 0...255. If an end byte was speci-
fied, data will be read in until the specified end byte is
recognized. If no end byte is specified (
end=0), only the
currently available bytes will be read in. Default is
end=0.
flush= defines the use of the port input buffer. In case
flush=0, all characters will be read in, even when they
occurred at the port long before the port was opened
with the
OPEN command. flush=1 however clears the
input buffer in the moment, the
OPEN command for that
port occurs in the program run. Default is
flush=0 (all
data stored in input buffer will be kept).
wait= specifies whether the program is to wait until all
characters have been transmitted over the port, or not.
wait=0 will continue the program after the transmission
of data has been initialized.
wait=1 will halt the pro-
gram until all characters have been transmitted. Default
is
wait=0.
