8.4.2 Programming for Data Communications
Setting the Communications Parameters
Use the OPEN "COM:" statement to set the communications parameters.
[ 1 ] BHT-3000/BHT-4000/BHT-5000
*1
The HS (High Speed) is available only in file transmission between the BHT-4000 and host
computer by using Transfer Utility. It requires the RS-232C interface specially connected.
Refer to the "BHT-4000 User’s Manual."
*2
The 38400 bps is available in the BHT-3000/BHT-4000/BHT-5000. Note that in the BHT-
3000/BHT-4000, the direct-connect interface port should be selected.
*3
The RS control is supported in the BHT-4000/BHT-5000.
*4
The ER control is supported when the direct-connect interface is selected in the BHT-4000.
[ 2 ] BHT-6000/BHT-6500/BHT-7000/BHT-7500
■ For optical interface
Parameters other than the transmission speed are fixed (Character length = 8 bits, Parity =
None, Stop bit length = 1 bit), since the physical layer of the optical interface complies with the
IrDA-SIR 1.0.
