5.0 Hayes Emulation Mode
• Dial Command Modifiers. Several modifiers can be used with the
basic D (dial) command to alter dialing operations. The modifiers
are explained below.
Dial Command Modifiers:
L — Links a phone number to another number to be dialed as an
alternate
P — Sets pulse-dialing mode
S=m — Dial number stored at memory location m
T — Sets tone-dialing mode
W or : (colon) — Wait for dial tone before proceeding
, (comma) — Pause for 2 seconds
; (semicolon) — Return to command state after dialing
@ — Wait for silence
! (exclamation) — Flash
With few exceptions, dial-command modifiers function only if they are
used in a command line with the D command, or if they are included
in a stored number. A carriage return or period must be used at the
end of a dial string.
An example of a command line with two dial modifiers is shown below.
AT DT 9,555-1212
The modifier T instructs the modem to tone-dial. The comma instructs
the modem to pause after dialing 9 before it dials the remaining digits.
• Missing Parameter. A missing parameter is interpreted as a zero.
For example, the E command (echo) can be sent as either E0 or E1,
but if an E alone is sent, the Modem interprets it as if an E0 was sent.
• Command Buffer. The command buffer holds a maximum of 40
characters. If the command line exceeds 40 characters, the modem
refuses to execute any portion of the command line and sends an error
message. The AT at the beginning of the command line, control
characters, and spaces do not take up space in the command buffer.
Punctuation (except for spaces) does take up space in the command
buffer.
