Options

The only option that is specific to PAP is the open retry option, which is defined as following:

#define PAP_OPT_OPENRETRY0x2120  /* PAP open retry count */

This option, used with the OTConnect provider function, forces PAP to retry opening a connection a specific number of times before failing.

In order to use any option with PAP, you must indicate which protocol the option is intended for. To do this, you use a constant for the PAP protocol in the level field of the TOption structure when you specify an option.

#define ATK_PAP   'PAP '

With PAP, you can also use the generic OPT_ENABLEEOM, OPT_CHECKSUM and OPT_SERVERSTATUS options, which are described in "Specifying PAP Options".
