9600, 19200, 38400, 57600, 115200,
460800
(Note1)
or 4M
(Note2)
bps
300, 600, 1200, 2400,
4800, 9600, 19200,
38400, 57600 or 115200 bps
Character length 8 bits 7 or 8 bits
Vertical parity None Even, odd, or none
Stop bit length 1 bit 1 or 2 bits
Note1: 460800 bps is only possible when communicating from one BHT-604Q unit to another or with
the CU-621.
Note2: 4 Mbps is only possible for communication with the dedicated CU-611 unit.

System Mode
Refer to “Chapter 4 System Operation” – “4.4.3 SYSTEM MENU Configuration.”

BHT-BASIC
To set the transmission speed, character length, vertical parity, and stop bit length (For the IrDA interface,
set the transmission speed only), use the OPEN “COM:” statement in BHT-BASIC.
OPEN “COM: ... ” Opens the interface port selected in System Mode.
OPEN “COM1: ...” Opens the IrDA interface port for data transmission, irrespective of the setting in
System Mode.
OPEN “COM2: ... ” Opens the direct-connect interface port for data transmission, irrespective of the
setting in System Mode.
Note that it is impossible to open both the IrDA and connector interface ports concurrently.
Through the interface port opened by the OPEN ”COM:” statement, the XFILE statement transmits a
designated file.
