In BHT-BASIC 3.0
To set the transmission speed, character length, and the number of stop bits, use the
OPEN "COM:" statement in BHT-BASIC 3.0.
OPEN "COM: ... " Opens the interface port selected in System Mode.
OPEN "COM1: ... " Opens the optical interface port for data transmission
routing through the CU-5000, irrespective of the setting
in System Mode.
OPEN "COM2: ... " Opens the direct-connect interface port for direct data
transmission, irrespective of the setting in System Mode.
Note that it is impossible to open both the optical interface port and the direct-connect
interface port concurrently.
Through the interface port opened by the
OPEN "COM:" statement, the XFILE
statement transmits a designated file.
