Description
S90 DTE Rate = VF. Register allows the DTE’s data rate to be equal to the VF
(telephone line) data rate. If Enabled, the data rate between the DTE and
modem is the same as the modem’s VF data rate. As a result, when the
modem is in Data mode, the speed of the data passed between the modem
and DTE occurs at the VF data rate.
Register has the following values:
0 = Disable
1 = Enable
The factory setting is Disable.
