Perform automatic tone dial of 102. Modem will return
OK. The user will not receive <DLE> events for dial
tone, ring-back, busy, and quiet since the detectors are
disabled. See Table 117 for details on active detectors.
The user is free to dial manually using the +VTS com-
mands to create the DTMF digits.
Generate DTMF 1 digit for 200 ms.
Generate DTMF 0 digit for 200 ms.
Generate DTMF 2 digit for 200 ms.
The user will not receive <DLE> events for dial tone,
ring-back, busy, and quiet since the detectors are dis-
abled. See Table 117 on page 190 for details on active
