If your
WaveWare v
9
Series Paging System
is configured to operate using
TAP
Non-Verbose mode, the paging system
will respond only with an initial response code of:
211<CR>
Following the first part of the
TAP
Message Block response, if the input buffer of the paging system has capacity for
another
TAP
message block, the paging system will send the following message.
<ACK><CR>
The
<ACK><CR>
response can be used as a flow control method to prevent overflow and lost messages. As alternative
flow control methods, you can use either hardware or software flow control. If the paging system is configured for
hardware flow control mode, the RS-232
CTS
signal will be de-asserted when the input buffer doesn’t have capacity for
another
TAP
Message Block, and re-asserted when capacity exists in the input buffer. If the paging system is configured
for software flow control mode, an
XOFF
Character (0x11) will be output in the response string to indicate the input buffer
doesn't have capacity for another
TAP
Message Block. When capacity is available, an
XON
Character (0x13) will be
output.
When the Host Device delivers a
TAP
Message Block and a checksum error occurs, the paging system will respond with
an error message and a
<NAK><CR>
, which tells the Host Device to resend the transaction.
See Appendix D – TAP Response Codes
for more information on paging system response messages. If the
TAP
Message Block checksum is OK, but the Message Block violates formatting rules, the paging system will respond with an
error message and an
<RS><CR>
, which tells the Host Device to abandon the transaction. An example error message
sequence follows:
514 Checksum Error – Exp. 2:9 Got 2:X<CR><NAK><CR>
PAGING SESSION LOGOUT
The Paging Session Logout mode allows a Host Device, sometimes called a Remote Entry Device, to stop
communications with the paging system. With the
WaveWare v
9
Series Paging System
, the Logout process is optional.
The
WaveWare v
9
Paging System
will automatically login a Host Device and process the paging message if it
recognizes a properly formatted
TAP
message block at any point in its operation.
To initiate a logout (disconnect sequence) the
Host Device
should send the following to the paging system:
<EOT><CR>
Upon recognizing a logout command, the paging system will respond with:
PAGING EXCHANGE DISCONNECT<CR><ESC><EOT><CR>
