- This document uses a mono-spaced font (Monaco) that contains tabs that
- are 8-spaces wide (looks nice on our unix box). You may have trouble
- viewing this document if your font and tabs are not of a similar size.
-
- This document is a list of modem commands for the Prometheus-made "LineLink
- 144e" modem. It is a v.32 data/fax/voice modem sold for $99(US) through
- MacWarehouse (tel:1-800-255-6227) that has attracted a lot of attention
- lately. Please see related files such as the "lineline-144e-faq" for more
- general information about the modem and its use, if you don't already own
- one. The FAQ provide helpful information, while this document is inteneded
- only for owner reference purposes (not very handy without the modem).
-
- This document is compiled from several sources. The information contained
- herein is assumed to be correct, but it is used at your own risk. The sources
- include the LineLink manual, Hayes modem command sets, Supra modem command
- sets, Global Village modem command sets, and Fax Class 1/2 documents. Aside
- from indirectly quoting manuals from modems I have purchased, I found some
- information through Internet, and in general found the Prometheus BBS to
- be lacking (for LineLink Mac users).
-
- The LineLink modem comes with a "near-useless" 28 page manual. The manual
- has very little technical info about its command set. This manual lacks
- information about commands such as "%An" registers S16, S18, S21, and S22.
- As far as I have been able to gather, the complete modem command set is:
- --------------------------------------------------------------------------
-
- Command Mode:
- =============
- The LineLink modem must be in command mode before commands are typed. The
- modem enters the command mode when it is turned on or reset, when it loses
- a connection or when it is in the data mode and the escape sequence is
- generated.
-
- Data Mode:
- ==========
- The LineLink modem is in the data mode after it makes a connection with
- a remote modem and sends appropriate the CONNECT response. Everything it
- receives from the DTE is considered data that it sends over the telephone
- line to the remote modem.
-
- The following comments apply to the modem commands that follow:
-
- - Commands can be entered in a string, with or without spaces. The "delete"
- or "backspace" key will be ignored by the modem.
-
- - A command line can contain one command or a series of commands, but
- cannot exceed 40 characters in length.
-
- - Commands that accept numeric arguments, when not specified, will default
- to 0. Numeric values are denoted by the variables "n" or "r"
-
- - The AT (attention) command preceds all commands (except A/).
-
- - Your command line must end with a <CR> (except when using A/).
-
- - The escape sequence "<GT>+++<GT>" lets you return to command mode without
- breaking your connection with a remote modem. <GT> represents a guard
- time which is a delay before and after the escape sequence.
-
- - Factory default settings are denoted with an asterisk, and are stored
- in non-volatile memory.
-
- Direct Commands Description
- =============================================================================
- AT Attention command prefix (precedes all except A/)
- A/ Repeat last command.
- <GT>+++<GT> Escape Code sequence. The guard time <GT> must be set
- using register S12. This sequence is thus preceded and
- followed by a minimum time period of no transmission.
- <CR> Carriage Return. Terminate current connection attempt
- during the dialing or protocol negotiation process.

-
- S Registers Decription
- =============================================================================
- S0 Number of Rings to Auto Answer (0-255. Default is 0 = disabled).
- S1 Count incoming rings (0-255). Resets after 8 secs after last ring.
- S2 Escape Code character (0-255 Default is 43 "+"). Values greater
- than 127 disable the feature, preventing a return to command mode,
- unless a hang-up or DTR transition takes place.
- S3 Carriage Return Character <CR>. (0-127. Default is ascii 13). Used
- to signal the end of the command line string in command mode.
- S4 Line Feed Character <LF>. (0-127. Default is ascii 10). Used when
- the modem sends Result Codes. Cannot be totally disabled.
- S5 Backspace Character <BS>. (0-32, 127-255. Default is ascii 8).
- S6 Wait for Dialtone (2-255. Default is 2 seconds). When the modem
- executes a dial command. This tells how long to wait after going
- off-hook before beginning to dial.If the modem doesn't receive a
- dialtone before S6 elaspes, then will get a "NO DIALTONE" response.
- S7 Wait time for carrier. (1-120. Default is 40 seconds). This tells
- the modem how many seconds to wait for a remote modem's carrier
- signal before hanging up and returning a "NO CARRIER" response.
- S8 Pause time for comma. (0-255. Default is 2 seconds). The amount of
- time to pause each time the modem encounters a comma in the dial
- command line. This is useful when dialing through a PBX or to stop
- call-waiting (ATDT *70,555-1212).
- S9 Carrier Detect response time. (1-255. Default is 6 tenths seconds).
- This is how long the remote modem's carrier (in 1/10 seconds) must
- be present, so it cannot be mistaken for a busy signal, ring, or
- voice. Increasing the time reduces the chances the modem will
- mistake line noise for a carrier signal.
- S10 Carrier Loss Time. (1-255. Default is 14 tenths seconds). This is
- the time (in 1/10 seconds) between the loss of a remote modem's
- carrier signal and the LineLink disconnecting. The value can be
- increased to ignore carrier dropouts on a noisy line, or they
- can be reduced to make the modem automatically hang up and allow
- call-waiting calls to ring through. To ignore the Data Carrier
- Detect and have the LineLink act as if the remote modem's carrier
- is always present, set this value to 255. Setting this to a value
- less than the value in register S9, causes the modem to disconnect
- when it detects a momentary carrier loss, because register S10
- expires before the carrier respone time expires.
- S11 Touch-Tone (DTMF) Dialing Speed. (50-255. Default is 75 ms). This
- is the speed of dialing (in milliseconds) during which the DTMF
- tones are held for each digit (it does not affect pulse dialing,
- which is fixed at 10 pulses per second).
- S12 Guard Time Value. (0-255 in 1/50 seconds. Default 40/50 seconds).
- This sets the guard time <GT> delay required before and after the
- escape code sequence (usually "<GT>+++<GT>") before returning to
- the Command mode.
- S14 Bit-mapped register (default value is 170) that provides the
- following functions (equivalent commands shown in parentheses):

- 1 0 1800 Hz guard tone(&G2)
- 1 1 Reserved for later use.
- S25 DTR Delay. When command &M1 is in effect, this specifies the number
- of seconds (default = 5) that the modem waits after a connection
- has been made before examining the DTR signal. This delay allows
- an asynchronous terminal to be detached from the modem and a
- synchronous terminal connection made while remaining in the Data
- Mode. After this delay S25 reverts to hundredths of seconds.
- S26 RTS/CTS Delay. This is the number of 1/100 seconds (default is 1)
- that specifies the time delay between RTS and the CTS response.

- 1 0 BELL 103/212A (B1)
- 0 1 CCITT V.23 (B2)
- 1 1 CCITT V.23 (B3)
- S30 Automatic Timeout (in tens of seconds). This specifies the number of
- seconds the modem waits with no activity, before disconnecting (in
- 10 second increments). Default is 0, which disables it.
- S36 Negotiation Fallback. When the initial attempt to connect in error-
- control mode fails, this specifies what occurs next (default = 7).
- 0 = Hang up
- 1 = Attempt a direct asynchronous connection
- (&Q0)
- 2 = UNKNOWN???
- 3 = Attempt an asynchronous connection using automatic
- speed buffering (&q6).

- (MNP 2-4); if fails, attempt a direct async connection.
- 6 = UNKNOWN???
- 7 = Attempt a CCITT V.42 Alternative Protocol (MNP 2-4).
- Note: The selected fallback option can be initiated immediately
- with S48.
- For example, a connection attempt using the MNP can be forced by
- setting
- S48=128 and S36=5 or 7.
- S37 Maximum DCE Line Speed S37 selects the speed (for all modes except
- CCITT V.24bis) at which the modem attempts to connect with a
- remote modem; the speed selected will be the highest DCE speed
- supported by both modems (see S93 for CCITT V.25bis modes).
- 0 = Speed of last AT command issued
- 1 = 75 bps
- 2 = 110 bps
- 3 = 300 bps
- 5 = 1200 bps
- 6 = 2400 bps
- 7 = 4800 bps
- 8 = 7200 bps
- 9 = 9600 bps
- 10 = 12000 bps
- 11 = 14400 bps
- S38 Delay Before Forced Hangup. This specifies the number of seconds the
- modem waits when in error-control mode (&Q5) before disconnecting
- (default is 20). This occurs after receiving the command to hang up
- or a DTR on-to-off transition. If set to 0, the modem does not wait
- for data in the buffers to clear (gives NO CARRIER response). If
- the register is set to a value between 0 and 254, the modem will
- wait the number of seconds, or until all data has been transferred,
- before hanging up. If set to 255, the modem will not hang up until
- all data is transferred.

- 136 = Disable Compression.
- 138 = Enable Compression.
- S48 V.42 Feature Negotiation (values of only 0,7, or 128). This defines
- whether feature negotiation is to be performed by the modem. The
- feature negotiation process allows the modem to ascertain the
- remote system's capabilities. If these capabilities are already
- known and negotiation is not necessary, this can be skipped.
- 0 = Disable Negotiation, proceed with LAPM.
- 7 = Enable Negotiation (default).
- 128 = Disable Negotiation, fallback per S36 setting.
- S49 Minimum Buffer Size (in bytes). Default is 10 bytes. This specifies
- the minimum size of the buffer used in error-control or automatic
- speed buffering mode. Should be less than S50.
- S50 Maximum Buffer Size (in bytes). Default is 200 bytes. This specifies
- the maximum size of the buffer used in error-control or automatic
- speed buffering mode. Should be greater than S49.
- S63 Leased-Line carrier power level in dBm (0-15. Default is 0). This
- specifies a carrier level value that is not to be exceeded.
- S82 Break Signaling Technique (values of only 3,7, and 128). This gives
- a method of break signal handling for CCITT V.42 communications:
- in-sequence, expedited, and destructive. Break signals provide a
- way to get the attention of the remote host. The break type used
- depends on the application.
- 3 = Expedited signaling used regardless of sequence in
- transmitted and received data; current data integrity
- is maintained.
- 7 = Destructive signaling used regardless of sequence of
- transmitted and received data; data in process at that
- time is destroyed.
- 128 = In-sequence signaling used as data is transmitted and
- received; data integrity is maintained ahead of and
- immediately after the break.
- S86 Connection Failure Result Code (values of 0, or 4-15). This helps to
- determine the cause of a connection failure. When the modem issues
- a NO CARRIER result code, a value is written to this S-register.
- To read this register following the connection failure, issue an
- ATS86? <CR>. The modem will report one of the values below.
- 0 = Normal hang up; no error occurred.
- 4 = Physical carrier loss.
- 5 = Feature negotiation failed to detect presence of another
- error-control modem at the other end.
- 6 = Other error-control modem did not respond to feature
- negotiation message sent by this modem.
- 7 = Other modem is sych-only; this modem is async-only.
- 8 = Modems could not find a common framing technique.
- 9 = Modems could not find a protocol in common.
- 10 = Incorrect feature negotiation sent by other modem.
- 11 = Sync information (data of flags) not received from
- other modem. Modem waited 30 seconds before hanging up.
- 12 = Normal disconnect initiated by other modem.
- 13 = Other modem did not respond after many transmissions of
- the same message. Modem made 10 attempts, then hung up.
- 14 = Protocol violation occurred.
- 15 = Compression failure.

- Note: Multiple occurences may contribute to a NO CARRIER message;
- Register S86 only records the first event that occurred.
-
- =================
- The LineLink firmware DOES support caller ID detection. The modem will
- display the caller id it receives from the phone co. The only problem
- is the modem will then crash and require a powercycle to get it back
- because the LineLink lacks a relay switch on its board.
-
- To try the caller ID yourself do the following: enter "AT#VS4" <CR> after
- the OK. Set the port speed to 19.2k and enter "AT#CC1" <CR> to display
- formatted caller id output.
