Here's how you can determine the status of flow control inside the EF Device:
•
EF2280 (Firmware Version 1.xx), EF200, EF1210:
Flow control is
set to "Automatic" meaning that the unit will not use flow control until it
senses that a cable is connected to the unit that has pins 7 and 8 active.
At that point, the EF Device will assume that flow control is required for all
commands. If you connect to the unit with a cable that does not have
flow control, the EF Device will limit communications with the host since
the EF Device is expecting RTS and CTS to be active. You will still be able
to communicate to the unit, but the rate will be much slower than normal.
To reset the flow control of the unit, cycle power. If the unit powers up
with no cable attached, flow control will be disabled until such time that a
cable with RTS and CTS is connected.
•
EF2280 (Firmware Version 2.0x):
Flow control can be set to "Off",
"On", or "Automatic" via RS-232 commands. "Off" means that flow
control is never enabled and you may connect to the unit with a cable that
supports or doesn't support flow control. "On" means that flow control is
always enabled. You must have a cable that supports RTS or CTS;
otherwise, you will not be able to communicate with the unit. "Automatic"
means that the unit will not use flow control until it senses that a cable is
connected to the unit that has pins 7 and 8 active. At that point, the EF
Device will assume that flow control is required for all commands. If you
connect to the unit with a cable that does not have flow control, the EF
Device will limit communications with the host since the EF Device is
expecting RTS and CTS to be active. You will still be able to communicate
to the unit, but the rate will be much slower than normal.

EF2280 (Firmware Version 2.1.0 or higher):
Flow control can be
set to "Off", "On", or "Automatic" via RS-232 commands or via the front
panel under V

. "Off" means that flow control is
never enabled and you may connect to the unit with a cable that supports
or doesn't support flow control. "On" means that flow control is always
enabled. You must have a cable that supports RTS or CTS; otherwise,
you will not be able to communicate with the unit. "Automatic" means
that the unit will not use flow control until it senses that a cable is
