Command:  +FPR  Fixed DTE Rate 
Description:  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. 
Syntax:  +FPR=<rate code> 
Defined Values:   <rate code> 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. 
Reporting Current or Selected Values: 
 Command: +FPR? 
    Response: <rate code> 
    Example 1: 0 For automatic rate detection. 
    Example 2: 18 For 57600 bits/s. 
Reporting Supported Range of Parameter Values: 
 Command: +FPR=? 
    Response: (<rate code> range) 
 Example: (0,1,2,4,8,10,18) 
Command:  +FMI?  Request Manufacturer Identification 
Description    This command causes the modem to report the modem product manufacturer. 
Syntax:  +FMI?  
Typical Response:  Multi-Tech 
 OK 
Command:  +FMM?  Request Model Identification 
Description:    This command causes the modem to report the modem product model. 
Syntax:  +FMM?  
Typical Response:  V90 
 OK 
Command:  +FMR?  Request Revision Identification 
Description:    This command causes the modem to transmit one or more lines of information 
text identifying the modem version, revision level, or date. 
Syntax:  +FMR?  
Typical Response:  V3.001-V90_2M_DLS 
 OK
