7.1.3. <DLE> Commands (DTE-to-DCE)
The characters listed in the Code column of Table 111 are referenced throughout this document with the <>
notation. Simple action commands consist of a <DLE> character plus a simple action-command character (two
bytes total).

The DTE must shield any 0x10 characters in the voice data stream sent to the DCE to
avoid creation of a <DLE> simple-action command.
More efficient representation of two 0x10 0x10 characters in the voice data stream.
Clear transmit buffer of voice data during +VTX session.
Do nothing. Refresh +VIT Inactivity Timer.
Disable DTMF reporting.
Enable DTMF reporting.
Abort Voice Receive State started by the +VRX command.
Increase volume or gain during voice stream processing. For +VRX, increase the UBF
and UC0 receive gains by 3 dB. For +VTX, increase the UB8 and UB3 transmit gains by
3 dB. The voice driver should track this command and update the +VGR or +VGT setting.
Since this <DLE><u> command affects RS232 DAA and RS232 Si3000 gain registers,
the voice driver should maintain two sets of +VGT and +VGR. The voice driver will need
to know the +VLS state to determine if RS232 is connected to the Si3000 or the DAA.
This command is only processed during an active +VRX or +VTX operation.
Decrease volume or gain during voice stream processing. For +VRX, decrease the UB3
and UB8 receive gains by 3 dB. For +VTX, decrease the UB8 and UB3 transmit gains by
3 dB. The voice driver should track this command and update the +VGR or +VGT setting.
Since this <DLE><d> command affects RS232 DAA and RS232 Si3000 gain registers,
the voice driver should maintain two sets of +VGT and +VGR. The voice driver will need
to know the +VLS state to determine if RS232 is connected to the Si3000 or the DAA.
This command is only processed during an active +VRX or +VTX operation.
End Voice Receive State started by the +VRX command.
