+FPR - Fixed DTE Rate
This numeric extended-format parameter specifies the data rate at which the modem will
accept commands during on-line operation. It may be used to select operation at rates at
which the modem 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 modem. The specified rate takes effect following the
issuance of any result code(s) associated with the current command line.
The <rate> specified does not apply in On Line Data State if Normal Mode (Direct
Mode) of operation is selected.
Syntax +FPR=
Defined Values
Specifies the DTE-modem interface operation rate in bits/s with
a rate code. The available rate codes are:
0 Automatic detection (default)
1 2400 bits/s (executes +IPR=2400)
2 4800 bits/s (executes +IPR=4800)
4 9600 bits/s (executes +IPR=9600)
8 19200 bits/s (executes +IPR=19200)
10 38400 bits/s (executes +IPR=38400)
18 57400 bits/s (executes +IPR=57400)
If unspecified or set to 0, automatic detection is selected and
the character format is also forced to autodetect, +ICF=0.
If the rate specified is not supported by the modem, an ERROR
result code will be returned.
