Description
%VH
VoiceSpan Data Mode Control
Permits dynamic switching from simultaneous
audio and data mode to high-speed, data-only
mode. This affects only the transmit direction;
data continues to be received at a rate
determined by the settings of the remote
DataPort 2001. Setting %VH is valid only if the
local telephone is off-hook. Possible values of
%VH are:
%VH0
Audio and data
%VH1
Data only
%VF does not set a default value for %VH. If the
local telephone is off-hook when VoiceSpan
mode is established, the DataPort 2001 defaults
to audio and data mode.
Table B-3 shows how the setting of %VH, in
conjunction with the status of the phone,
determines what is transmitted.
