Manual Entry of a Page
Entry Device
PAGE CENTER Action
Comment
M<CR>
The Entry Device tells the PAGE CENTER
transmitter that it wants to manually send a
POCSAG page, by ending the M.
ENTER PAGER NUMBER:
The PAGE CENTER will respond within one
second of the M sequence signifying that the
Entry Device has successfully logged on to the
PAGE CENTER, and it is ready to receive
paging info. The PAGE CENTER begins by
responding with this prompt.
PagerID<CR>
The user responds with the ID of the pager he
wishes to page.
Enter Alpha Message:
or
Enter Numeric Message:
The PAGE CENTER responds with one of the
following messages, depending upon the type
of pager that the PagerID is assigned to.
Message<CR>
The user enters a message to send to the pager.
Sending Message...<CR>
The PAGE CENTER displays this message as it
sends the message to the pager.
MessageSent<CR>
or
Can't Deliver to xxxxxxx<CR>
or
Too Slow. Goodby.<CR>
or
Two many errors. Goodby.
<CR>
One of these messages will then be sent from
the PAGE CENTER, depending upon the
current situation with the page that was entered.
The serial port has a 45 second activity time,
and will force and end to the manual session if
the user does not complete the page in that
time.
7.2 TAP Protocol Issues
7.2.1 Timing
The PAGE CENTER will only wait for 15 seconds for a response to come back from the Entry Device. If a
response is not received before the time-out period, the PAGE CENTER will cancel the current transaction,
sending the <ESC> <EOT> <CR> sequence.
7.2.2 Line Feeds
The PAGE CENTER will ignore all <LF> characters it receives. The Entry Device may send a <LF> with any
<CR>.
XOFF
In the very unlikely event that the user enters more pages than the PAGE CENTER can queue up, the PAGE
CENTER will send the <XOFF> character before sending a carriage return. It will send the <XON> character
when buffer space is available for more pages. If the PAGE CENTER does not receive data within 10 seconds
after sending an <XON>, it will send another <XON>.
