Start Modem Data Mode (-SDA)
This command initiates the transmission of the modem data mode start sequence and causes
the DCE to switch to modem data mode.
Start Facsimile Data Mode (-SFX)
This command initiates the transmission of the fax data mode start sequence and causes the
DCE to switch to fax data mode.
Capabilities Query Response Control (-
SQR=n)
This command controls the response to a capabilities query.
Parameters: 0,1
n = 0
One-way response.
n = 1
Two-way response.
Set Capabilities Data (-SCD=n)
This command is used to read, add to, or establish the contents of the DCE’s capabilities
data structure. The capabilities elements (n) consist of pairs of hexadecimal numbers and
specify the capabilities information.
AT-SCD? Reads the current capabilities.
Error Reporting (-SER?)
This command asks the DCE for an error report. The DCE responds with either 0 (no error
found) or a pair of hexadecimal digits representing the error byte.
Set VoiceView Transmission Speeds (-
SSp=x, y, z)
This command specifies the data modulation schemes that are associated with the
VoiceView mode tones. The digits of the compound value represent burst speed (x),
recovery speed (y), and priority speed (z).
