5.2.2.18 +VPR - Select DTE/Modem Interface Rate (Turn Off Autobaud)

This command selects the DTE/modem interface rate.

Syntax

+VPR=<rate>

Defined Values

<rate>>

Decimal number corresponding to the DTE/modem interface rate where 0 = autobaud rate
determined by processing the AT command, and 1,2,3,4,8,16,24,48 correspond to multipliers of 2400
bps to determine the actual rate:

0 = Autobaud
1 = 2400 bps
2 = 4800 bps
3 = 7200 bps
4 = 9600 bps
8 = 19200 bps
16 = 38400 bps
24 = 57600 bps
48 = 115200 bps

Reporting Current or Selected Values

Command:

+VPR?

Response:

<rate>

Example:

For the default setting (Autobaud).

Reporting Supported Range of Parameter Values

Command:

+VPR=?

Response:

(<rate> range)

Example:

(0,1,2,3,4,8,16,24,48)

Result Codes

<rate> = 0,1,2,3,4,8,16,24,48.
