■
charalength
charalength is a character length or the number of data bits. It should be 8
(default) or 7 bits.
■
stopbit
stopbit
is the number of stop bits. It should be 1 (default) or 2 bits.
■
RS/CS
RS/CS
enables or disables the RS/CS control. It should be 0 (default), 1, 2, 3,
or
4, which corresponds to the following function:
As listed above, you can specify
RS/CS option for the direct-connect interface.
If you specify it for the IrDA interface, it will be ignored resulting in no run-time
error.
RS/CS option is also applicable to Busy control when the direct-connect inter-
face is used. To do so, interface cable connection should be modified. For
details, refer to the BHT User’s Manual.
Shown below is a coding sample for enabling the RS/CS control.
OPEN "COM:,,,,1" AS #16
■ timeout
timeout
is a maximum waiting time length until the CS signal goes ON after
the BHT becomes ready to send data. It should be 0 to 255 in increment of 100
ms.
Specification of zero (0) causes no timeout.
To make the direct-connect interface support timeout, the
RS/CS option should
be set to "2" or "3" so that the RD signal is regarded as CS. If any of "0," "1,"
and "4" has been set to the
RS/CS option, the value of the timeout option will
be modified.
The IrDA interface does not support timeout. If specified, the
timeout option
will be ignored resulting in no run-time error.
NOTE
The IrDA interface is compliant with the IrDA physical layer (IrDA-
SIR1.0), so the vertical parity, character length, and stop bit length are
fixed to none, 8 bits, and 1 bit, respectively. If selected, those parameters
will be ignored.
