Dialing operation

Like keyboard dialing, the Hayes dialing commands allow the user to initiate
a data call, as well as change certain dialing parameters. The commands
may be entered in either upper or lower case, but must be the same case
throughout the command line. Also the case must match the autobaud case.

Note: Hayes dialing does not allow for the Ring Again feature. If a call
is made to a busy number, that call is abandoned.

Table 182 "AT dialing commands" (page 466)
