+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 OnLine Data State if Normal Mode (Direct
Mode) of operation is selected.
