34 CHAPTER 5: USING THE MODEM
S14 Bit-mapped. Storable. Bit 1. Echo command characters (E CMD)
■ 0 = No echo
■ 1 = Echo
Bits 2 and 4 generate result codes (Q CMD)
■ 0 = Enable result codes
■ 1 = No result codes
■ 2 = Result codes enabled only when originate mode in effect
Bit 3. Verbose/numeric result codes (V CMD)
■ 0 = Numeric result codes
■ 1 = Verbose result codes
Bit 5. Tone / Dial (P and T CMD)
■ 0 = Tone dialing (T CMD) toner
■ 1 = Pulse dialing (P CMD)
Bit 7. Current operating mode.
■ 0 = Answer mode
■ 1 = Originate mode
S16 Test Status (Bit-mapped). Nonstorable. Bit 0 is Analog loopback (&T1 CMD)
■ 0 = No Analog loopback
■ 1 = Analog loopback active
Bit 2. Digital loopback (&T3 CMD)
■ 0 = No Local digital loopback
■ 1 = Local digital loopback active
Bit 3. Status of Local digital loopback initiated by remote mode
■ 0 = No Local digital loopback
■ 1 = Local digital loopback initiated by remote modem active
Bit 4. Remote digital loopback (&T6 CMD)
0 = No Remote digital loopback active
1 = Remote digital loopback initiated and granted by remote
Bit 5. Remote digital loopback with self test (&T7 CMD)
■ 0 = No Remote digital loopback active
■ 1 = Remote digital loopback with self test initiated and granted by remote
Bit 6. Analog loopback with self test (&T8 command)
■ 0 = No Analog loopback
■ 1 = Analog loopback with self test active
S18 Test Timer. 0 = Infinite test time. Any other value specifies the duration of the test.
Value: 0 - 255. Default = 0. Storable.
S19 Bit-mapped. Nonstorable.
Bit 0
■ 0 Mu-Law codec
■ 1 A-Law codec
Bits 1-2 are Auto Rob bit signalling mode detection
■ 00 Enable.
■ 01 Disable (64K).
■ 10 Enable (56K).
