Low-Cost, Embeddable 33,600 BPS Modem Module

Unspecified 

XE3314B AT Commands (continued)

%L - Read Received Signal Level - AT%L permits the

user to read the magnitude of the receive signal in dBm.

%Q - Read Line Signal Quality - AT%Q permits the user

to read the EQM value of the received signal.

\An - MNP Block Size - AT|An sets the block size for MNP

data packets.

n=0 Maximum 64 characters

n=1 Maximum 128 characters

n=2 Maximum 192 characters

n=3 Maximum 256 characters*

\Bn - Transmit Break - AT\Bn selects the duration of the

break signal sent. Break = n x 100 msec.

\Gn - Modem Port Flow Control -

n=0 No Modem Port Flow Control

n=1 XON/XOFF Port Flow Control

\Kn - Break control - AT\Kn determines how the modem will

handle a break signal.

Break received from host with Reliable link.

n=0 Enter on-line command mode; do not transmit

break

n=1 Purge buffers, immediately transmit break

n=2 Same as n=0

n=3 Immediately send break

n=4 same as n=0

n=5 Send break in sequence with data*

Break received from host with Direct link .

n=0 Immediately transmit break, then enter on-line

command mode

n=1 Immediately send break

n=2 Enter command mode but do not transmit break

n=3 same as n=1

n=4 same as n=0

n=5 same as n=1*

Break received from modem w Normal link.

n=0 Purge buffers, Immediately send break to the host

n=1 same as n=0

n=2 Immediately send break to the host

n=3 Same as n=2

n=4 Send break in sequence with data.

n=5 Same as n=2*

Host initiates break on Reliable link.

n=0 Purge buffers and immediately transmit break

n=1 Same as n=0

n=2 Immediately transmit break

n=3 Same as n=1

n=4 Transmit break in sequence w data

n=5 Same as n=4

\Nn - Error Control Selection - AT\Nn determines how the

modem will handle error control negotiations.

n=0 Normal mode, no error correction

n=1 Direct mode, no buffering, no error correction

n=2 Reliable mode, error correction required

n=3 V.42 Auto-reliable mode, accept either an error

controlled or non-error controlled link*

n=4 V.42 Reliable mode, LAPM required

n=5 MNP required

-Kn - MNP Extended Services - AT-Kn determines how the

modem handles MNP10.

n=0 No LAPM to MNP10 conversion

n=1 LAPM to MNP10 conversion*

n=2 LAPM to MNP10 conversion but no MNP Ex-

tended Service during V.42 LAPM answer mode detect.

+MS - Select Modulation - AT+MS sets the modulation and

available data rates in the format shown below.

AR+MS= a, b, c, d <CR>

a = modulation type

0 - V.21(300 BPS)

1 - V.22 (1200 BPS)

2 - V.22bis (2400 BPS)

3 - V.23 (1200 BPS Half Duplex)

9 - V.32 (9600 BPS)

10 - V.32bis (14,400 BPS)

11 - V.34bis (33,600 BPS)

64 - Bell 103 (300 BPS)

69 - Bell 212 (1200 BPS)

b = Automoce Selection

0 - Automode disabled

1 - Automode enabled

c = Minimum Data Rate in BPS

d = Maximum Data Rate in BPS
