(The converted
command will be
discarded without
being sent).
The command
was received by
the Unit, but the
step transition in
the communica-
tions sequence of
the protocol
macro is sus-
pended for either
of the following
reasons.
• The next step is
a Receive com-
mand.
• The Wait com-

Remedy
Correct the communica-
tions sequence.
Alternatively, adjust
*_P1(orP2)_PmrSgwSendT
imeoutCfg (Serial Gateway
Send Start Timeout Moni-
toring Time), as required.
Change
*_P1(orP2)_SgwDsblCmd
(Serial Gateway Prohibit

to FALSE.
Perform either of the follow-
ing:
Loop the RTS (RS)-CTS
(CS) signals of the Local
Unit.
Disable CTS control.
Input the RTS (RS) signal
from the Remote Unit to the
CTS (CS) signal of the
Local Unit and use CTS
control.
