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
