The “P” command controls how the costing of a call is done. Costing can be done in two
ways. Standard Cost Mode and Prepaid Cost Mode.
In Standard Mode, the cost counter counts up from zero to tally the total amount of
the calls placed by the user.
In Prepaid Mode, the cost counter is preset to an amount (the amount deposited by
the user) and the proceeds to count down, subtracting amounts from the total to
provide to the user the amount of money he has left.
Format:
Pxxxxxxxx
<CR>
P
= “P”
X
= 8 digit amount with leading zeros.
This is the total to be displayed by the “C” command above.
Response:
^P
<CR>
The CallShop Fone Display will respond with this confirmation message
Example:
P00000000
<CR>
This command sets the prepaid amount to zero, and so turns off the prepaid
function. The Cost Counter will act in Standard Mode,
P00002000
<CR>
This command will set the prepaid amount to 2000 units. If we were working
in dollars, then this would represent $20.00. Because the command sets a
value of greater than zero into the prepaid field, the Cost Counter will work in
Prepaid Mode,
Begin Call/End Call:
The “B” command causes both the duration counter and the cost counter to begin
simultaneously. This is very helpful to “begin” a call or “end” a call, as both counters stop at
exactly the same time.
Format:
Bxyz
<CR>
B
= “B”
x
= Begin / End
1 = Begin
0 = End
y
= Optional command to control how the call is charged.
If this character is a “C” then the Cost Counter will also be
cleared. In Standard Cost Mode this means setting the Cost
Counter to zero. In Prepaid Cost Mode, this means presetting
the Cost Count to Prepaid amount.
If this character is a “S” then the cost counter will be
incremented/decremented by the cost “Amount” (see the “C”
command). In Prepaid Cost Mode, the “Amount” is immediately
subtracted from the Cost
Counter. In Standard Cost
