Character

Explanation

 

 

!

Used to force the modem to perform a “hook flash” (i.e., hang up quickly and release)

 

operation. Although rapidly fading from use, this mechanism is sometimes used in office

 

phone systems to signal the local switchboard to listen for special codes to follow.

 

 

-

These characters are used only to make the field more readable. They are ignored by

( ) <SPACE>

the modem, and can be placed anywhere in the field.

 

 

,

The comma forces the modem to pause 2 seconds before continuing to dial. A typical

 

use of this feature would be when the UPS is connected to a local phone system which

 

requires you to dial ‘9’ to get an outside line. Some systems may need the modem to

 

pause for a bit after dialing 9 before an outside line can be assigned. In such an

 

instance, you might see the complete dial string looking like this: 9, 555-8243.

 

 

W

Like the comma, the W command causes the modem to wait before continuing. The

 

difference is that the comma imposes a fixed 2 second delay, while the W means “wait

 

for a dial tone”.

 

 

#

Used in pager display fields to signify the end of the number. Most pager service

 

equipment require that the pound symbol be used to terminate an entry.

 

 

R

Stands for “Reverse.” The R command is a prefix which tells the modem to connect with

 

an originate-only modem. If the modem on the remote end answers silently (without

 

asserting a carrier tone) you may be dealing with an originate-only modem. Such

 

modems are rare these days. The R should be prefixed to any digits dialed, i.e., R 9,

 

555-8325.

 

 

T, P

Select tone or pulse dialing. Only one of these can be used in a given number. They are

 

both prefixes, the T stands for tone (i.e., touch tone) and the P stands for pulse. By

 

default, the modem uses tone dialing. If the UPS is connected to a phone line which

 

requires pulse dialing, a P should be prefixed to the number, i.e., P 555-8325.

 

 

@

Use @ to dial a service that uses a recorded voice to request further information to be

 

tone-dialed, such as a password and a transaction code: 555-8325 @ 9876. The

 

modem dials the phone number, waits for one ring at the remote end, and then waits for

 

5 seconds before continuing to the next part of the dial string. The @ imposes a 5

 

second “quiet answer” pause.

 

 

*

Used in pager display strings to generate a separator character between fields in the

 

display window. For example, if the pager display string is 555*8325, it will appear in the

 

pager window as 555-8325.

 

 

;

Used to force the modem to return to command mode after dialing. Unless you are very

 

familiar with modems and know exactly what you’re doing, do not use this command.

 

 

?

This character, if present in a pager display string, will be replaced with the event ID

 

code before being transmitted to the pager service equipment (see Table 10 for the list

 

of ID codes and associated events). For example, if the modem is dialing a pager

 

because of a battery test failed, the ? character would be replaced with the number 1

 

before being transmitted, and the number 1 would then appear in the pager display

 

window at the same location in which it appeared in the pager display number field. The

 

? character has no meaning in a dial number (line 1) field, it should only be used in

 

pager display (line 2) fields.
