AT+IPR Cable interface port rate
Test command: AT+ICF=? Shows if the command is supported.
Test command
response: +ICF: (list of supported <format>s),(list of supported <parity>s)
Parameters:
<format>: Determines the number of data bits, parity bits and stop bits in the start/
stop frame.
<format> Description
0 Auto-detect
1 8 Data bits, 2 Stop bits
2 8 Data bits, 1 Parity bit, 1 Stop bit
3 8 Data bits, 1 Stop bit. Default value
4 7 Data bits, 2 Stop bits
5 7 Data bits, 1 Parity bit, 1 Stop bit
6 7 Data bits, 1 Stop bit
<parity>: Determines how the parity bit is generated and checked, if present.
<parity> Description
0 Odd
1 Even
2 Mark
3 Space, Default value
Description: This numeric extended-format parameter specifies the data rate at which
the DCE will accept commands, in addition to 1200 bit/s or 9600 bit/s (as
required in v25ter subclause 4.3). It may be used to select operation at
rates at which the DCE is not capable of automatically detecting the data
rate being used by the DTE.
Specifying a value of 0 disables the function and allows operation only at
rates automatically detectable by the DCE. The specified rate takes effect
following the issuance of any result code(s) associated with the current
command line.
Note: Only applicable for RS-232, dummy command on IrDA and USB.
Set command: AT+IPR=[<rate>]
Read command: AT+IPR? Displays the current <rate> setting.
Test command: AT+IPR=? Shows if the command is supported.
Test command
response: +IPR: (list of supported auto detectable <rate>s)[,(list of fixed-only
<rate>s)].
