State
There are four states in which the CTA 500
dm
can interface with a
computer.
Command State
No other device is connected, through the
network interface, to the CTA 500
dm
. The CTA 500
dm
can process
and respond to AT commands. When the CTA 500
dm
cannot
establish communication with the connected ICS, it is either in the
Commands State or in the Download State.
On-line Command State
A valid connection exists between the
CTA 500
dm
and another device through the network interface.
However, the CTA 500
dm
can still process and respond to most
AT commands.
When the selected rate adaptation protocol has no ßow control and
the CTA 500
dm
is in the On-line Command State, data may be lost.
Enter the On-line Command State from the On-line Data State using
the Escape Sequence (refer to
ÒEscape SequenceÓ on page 35
) or
using the DTR signal if &D is 1 (refer to
ÒSerial Interface Control
LinesÓ on page 56
).
Note:
You cannot enter the On-line Command State until the
CTA 500
dm
establishes communication with the connected
ICS.
Enter the On-line Data State from this state using the O command
(
ÒReturn to On-line Data StateÓ on page 34
).
