BHT-BASIC treats communications devices as
files. File and packet transfers therefore require first opening
the communications device file.
speed specifies the transfer speed in bps. (See the table below.)
If this parameter is omitted, the BHT uses the last setting,
which defaults to 9600 bps.

fileno can be any number
from 1 to 16 not currently in use by another file (data or bar
code device). Use the same number to send data packets to and
close the communications device file.
Note that always close bar code, Wireless LAN, and other communications
device files before opening this device. It cannot be used simultaneously
with other such devices.
Closing the communications device when it is no longer needed
conserves BHT power, increasing the time between recharges. →Closing
