Appendix A – TAP Interface Specifications - 12

PAGING OPERATION 

Paging transactions are transmitted in blocks of characters, where one transaction is sent per block.  Each 
block sent by the Host Device is acknowledged by the paging system.  The Host Device must wait for this 
acknowledgement before sending the next block.  The 

WaveWare Paging System

 provides 

acknowledgement in the form of an <ACK> character. 

The 

WaveWare Paging System

 supports TAP message blocks up to 253 characters in length, with a 235 

to 244 character message, from 1 to 10 characters for ID (pager number), plus 5 control characters, and a 3 
character checksum.  (Message field length is restricted as follows:  when a 1 character ID is used, a 244 
character message can be accommodated, and so on, for a total of 253 characters, such that when a 4 
character ID is used, a 241 character message can be accommodated.  The maximum ID field length of 10 
causes a maximum message field length of 235 characters).  A block always carries two fields with their 
associated carriage returns.  The message field may be empty, but it’s carriage return must be included in 
the data block.  The TAP message block format is as follows: 

 

<STX>ID<CR>Message<CR><ETX>Checksum<CR> 

The ID field is a one to ten character pager number.  Leading zeroes are not required.  The Message field 
accommodates up to 235 alphanumeric characters.   The Checksum field provides a checksum for the 
previous portion of the TAP message block.  See Appendix D – TAP Checksum Calculation, for sample 
code to create the checksum field. 

The Message field can be formatted as follows:   

 

For alphanumeric paging messages, all 7-bit ASCII “non-control” characters are valid except ^, ~, and 
_ (underscore) 

 

For numeric paging messages, valid characters are the numbers 0 through 9, - (hyphen), and space 

 

Control characters can be embedded into paging messages so that high end alpha pagers and paging 
data receivers can respond with formatted screen displays and with formatted serial output, as 
required.  Control characters (typically <CR> and <LF>) can be embedded in messages by using the 
Transparency Option.  The Transparency Option replaces a non-printable control character with the 
SUB (Hex 1A) character immediately followed by the control code offset by 40 Hex.  See Appendix G 
- Embedded Control Characters for details on how to embed control characters in paging messages. 

The WaveWare TAP interface supports ID field lengths from 1 to 10 digits.  The ID field can be formatted 
using two different methods, as follows: 

 

Method 1 - ID field lengths from 1 to 4 digits will cause a pager database lookup.  ID fields of this 
format must contain numeric digits only.  The numeric ID value will be compared to the ID values 
stored in the 

WaveWare Paging System

’s onboard pager database. 

 

Method 2 - ID field lengths from 5 to 10 digits will cause Extended ID processing.  Extended ID 
processing assumes that the last 3 digits of the ID field define paging message encoding attributes, 
while the preceding digits define the pager capcode.  Extended ID processing allows you to avoid the 
process of configuring a pager database in the 

WaveWare Paging System

.  See Appendix E – 

Extended ID Processing for details on how to format the ID field. 

When the Host Device delivers a TAP Message Block to the 

WaveWare Paging System

, if the message 

block is properly formatted, and a 1 to 4 digit ID field matches the pager database, the paging system will 
respond with an initial response code as follows:
