Echo

Unit will or will not echo back commands that are sent to it. Set to lower case "e" for echo on.

Some applications need to detect a certain character in order to perform an operation. When this toggle is set to "c", the unit places a "$" character before each data string. This includes detail data strings such as Ring, Off hook, On hook, and Hook flash (see toggle "D,d"). Also when c is set, the dashes are removed from the telephone number field. The telephone number justification remains as set by the "X,x" toggle.

Two different data formats can be sent by the unit. The limited format sends the line number, date and time, phone number, inbound/outbound indication, and name (if available). The comprehensive format sends the same along with the duration of the call, checksum indication, and number of rings. The comprehensive format is strongly recommended. More detail on these formats on page 9.

The unit can block or pass incoming calls based on a match against phone numbers pre-loaded into the on-board memory. The "u" toggle turns on the Block/Pass feature. The "K,k" toggle determines whether the unit blocks or passes calls that match these numbers.

Set "K" to pass all calls until defeated. Set "k" to block all calls until defeated. These toggles can be defeated by either the "W" command sent by the host computer or signal sent by the internal memory when a phone number match is found.

The unit is capable of delivering a data stream to the host computer immediately as the call arrives, when the call terminates, or both. For an inbound call, immediate data delivery allows the Caller ID information to be utilized before the call is answered for purposes of database queries, call routing, etc. Delivering the data stream after the call ends provides additional information about the call to the application program such as, the duration of the call and the number of rings before the call was answered. If lower case "a" is set, data is sent as defined by the "S,s" toggle.

For this toggle to affect operation "a" must be set. If call data is to be sent before the call is answered, set toggle to "S". If call data is to be sent only after call terminates, set toggle to "s". If call data is to be sent before and after the call, set toggle "A".

When this toggle is set to "B", the first ring to the output jack on each line is suppressed. Since the Caller ID stream is sent between the first and second rings on the telephone line, this prevents the call from being answered before the information is sent. However, in some cases, hearing the first ring might be essential for the user to respond to the call in a timely manner. If this is true, set this toggle to "b".

Some software applications may need additional call data. When the lower case "d" toggle is selected, the unit can provide an indication for Ring, Off hook, On hook, and Hook flash. The format is as follows: line number (nn); space; and either a R (Ring), F (ofF hook), N (oN hook), or H (Hook flash). The date and time (HH:MM:SS) follow at the same offset as the date/time field in the comprehensive format. In the detail mode, the time is delivered in a 24 hour format. (Please note: If the "c" toggle is selected, a leading "$" will be added to the above data string). For more information see the section on Detail Mode on page 8.

For basic Caller ID applications, use the upper case "O". If complete call accounting is required, use lower case "o". The lower case "o" instructs the unit to deliver for both inbound and outbound calls.

When set to lower case "t", unit will monitor for DTMF touch tones on inbound calls. This toggle is used primarily for voice mail and Integrated Voice Response (IVR) applications. The DTMF digits dialed during the call will be displayed in the "Name" field on the call record sent at the end of the call. If the Caller ID service provides the caller's name, the name will still appear in the call record sent at the beginning of the call. (If both the Caller ID name and the DTMF digits are needed use the upper case "A" to have the unit deliver both start and end records.)
