Nokia 6090 - EB Break Handling in Error Control Operation; EFCS 32-Bit Frame Check Sequence

Nokia 6090 AT Command Set 52
+EB Break Handling in Error Control Operation
This command controls how break signal is handled. Operation mode for a break
signal to be sent to remote end is selected with <break-sel>, and <timed> specifies if
break length is signalled to the remote end. Default length of a break signal to be
sent to local DTE is specified with <def-length> for the cases where break length is
not received. These settings are only used in transparent data call (see command
+CBST at page 14) with V.42 enabled (see command +ES at page 53). (V.25ter)
Syntax:
AT+EB=[<break-sel>[,
<timed>[,<def-length>]]]
Set break parameters.
Default options are 1, 0, 30.
AT+EB?
Query current setting.
Response is +EB: <break-sel>, <timed>,
<def-length>.
AT+EB=?
Show supported values.
Response is +EB: (list of supported
<break-sel>’s), (list of supported
<timed>’s), (list of supported <def-
length>’s).
Parameters:
<break_sel>
0
ignore break
1
break sent to data buffer (non-expedited),
subsequent data is retained (default)
2
break sent immediately (expedited),
subsequent data is retained
3

subsequent data is cleared
<timed>
0
break length not signalled to remote end
(default)
1
break length signalled to remote end
<length>
0
do not deliver break to DTE
1 to 254
default break length in 0,01 second
periods (default 30)
+EFCS 32-bit Frame Check Sequence
This command controls the use of the 32-bit frame check sequence option in V.42
error control mode. 32-bit FCS is not supported. This command has no effect on the
product, because only 16-bit FCS is supported. (V.25ter)
Syntax:
AT+EFCS=0 Select 16-bit FCS. Default option is 0.
AT+EFCS?
Query current setting.
Response is +EFCS: 0
AT+EFCS=?
Show supported values.
Response is +EFCS: (0).
