Desired DCE Speed. Values marked by M are reserved exclusively for analog modem
features. Those marked by I are used only for ISDN V.110 data calls. Values with no
symbol can be used for analog modems and V.110 calls. For V.110 calls, the
corresponding speed value is used disregarding the modulation specified. (e.g.
S37=18 will result in a V.110 connection at 12000 bps.). Storable.
