Defined Values
<off> Determines the threshold, in octets, above which the modem will generate a flow off signal. Applicable in
Synchronous Access Mode. The <off> range is 20 -7000. Default <off> value is 128. For the <on> and
<off> subparameters, the input buffer is assumed to reside between the modem’s V.24 interface and the
Synchronous Access protocol layer; i.e., the buffer count includes all octets, including EM codes, received
from the DTE, with the exception of XON and XOFF if these are used to signal <modem-by-DTE> flow
control. The modem returns the ERROR result code if the DTE specifies that the <off> subparameter be
set to a value less than or equal to the <on> subparameter; in this case, the current parameter value
settings are set to default values.
<on> Determines the threshold, in octets, below which the modem will generate a flow on signal. Applicable in
Synchronous Access Mode. The <on> range is 10 -5000. Default <on> value is 64.
<report_period> Not supported. A fixed value of zero is used and reported.
