Circuit Card Description and Installation
Note: The parity determined here overrides the parity downloaded from
the system. Also, the T (t) must be entered in the same case as the A (a).
If you entered uppercase A for the Baud Rate, you must enter upper case
T for the parity.
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 160 provides a list of the AT dialing commands.
