After initiating a page, and receiving the ID= prompt, the Entry Device can respond in one of two
different ways. One way puts the OSMAC Base into an Automatic Mode, and the other ways puts it
into a Manual Mode.
Automatic Entry of a Page
Entry Device OSMAC Base Action Comment
<ESC>PG1<CR>
The Entry Device tells the OSMAC Base
transmitter that it wants to automatically send a
POCSAG page by ending this sequence.
<CR><ACK><CR>
or
<CR><NAK><CR>
or
<ESC><EOT><CR>
The OSMAC Base will respond within one second
of the ACK sequence signifying that the Entry
Device has successfully logged on to the OSMAC
Base. If paging entries cannot be accepted, it will
respond with the NAK sequence or the ETX
sequence, which should force the Entry Device to
disconnect.
<ESC> [p <CR> This "go ahead" sequence tells the Entry Device
that it is OK to go ahead and send over the
information for the first page or pages. The p is
always the lower case "p".
<STX>
PagerID<CR>
Message<CR>
<ETX>
Checksum <CR>
This Pager/Message Sequence Block tells the
OSMAC Base the ID (the Pager Number in the
OSMAC Base's database) of the pager this the
Message is to be sent to. The checksum is
computed as shown later in this document. The
total number of characters sent from the Entry
Device per sequence should not exceed 255.
Repeat the above
Pager/Message
Sequence Block
as many times as
required, if more
pages are to be
sent.
<EOT> <CR> When the Entry Device does not want to send any
more pages, it sends this EOT sequence, to tell
the OSMAC Base that it is finished with this
automatic session.
Pages Accepted <CR>
or
Invalid Page
Entered<CR>
or
<Message><CR>
One of these status messages will be returned at
the end of the session. They are for information
purposes only.
<CR><RS><CR> This is only sent if there was an error in this
session, probably due to an invalid pager ID or a
message type mismatch.
PAGING EXCHANGE
DISCONNECT <CR>
<ESC> <EOT>
The End of Transaction message sent from the
OSMAC Base to the entry device, telling it to
disconnect.
