- info - remote device capability database
-
- DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN
- The iiiinnnnffffoooo subdirectory in the _H_y_l_a_F_A_X spooling area holds
- information about the capabilities and status of devices
- that have been called. One file exists for each device,
- with the filename created from the remote device's fully-
- qualified phone number. Files have a simple ASCII format.
- Each line is of the form
- [&&&&]ttttaaaagggg: _v_a_l_u_e
- where a _t_a_g identifies a capability and a _v_a_l_u_e is either a
- string, number, or boolean value. An optional ``&'' at the
- front of the line indicates that the tag's value is _l_o_c_k_e_d
- _d_o_w_n and should not be updated by the server. This facility
- is useful for restricting the capabilities used with a
- particular machine.
-
- The following items are recorded:
- TTTTaaaagggg TTTTyyyyppppeeee DDDDeeeessssccccrrrriiiippppttttiiiioooonnnn
- calledBefore boolean device has previously answered at this number
- dialFailures number count of consecutive failed dial operations
- lastDialFailure string reason for last failed dial operation
- lastSendFailure string reason for last failed send attempt
- maxPageWidth number maximum page width in pixels
- maxPageLength number maximum page length in millimeters
- maxSignallingRate string maximum signalling rate (bits/sec) to use
- minScanlineTime string minimum scanline time
- pagerMaxMsgLength number length of longest allowed text message
- pagerPassword string password string send to service provider
- pagerSetupCmds string commands for setting up modem for a specific service provider
- pagerTTYParity string parity & # bits configuration for IXO/TAP communication
- pageSource string parameter to tell the paging central who we are
- pagingProtocol string protocol (IXO or UCP) for this provider
- remoteCSI string remote device Called Subscriber Identification
- sendFailures number count of consecutive failed send attempts
- supportsHighRes boolean accepts 196 line/inch images
- supports2DEncoding boolean accepts Group 2D encoding
- supportsPostScript boolean accepts Adobe POSTSCRIPT transfer protocol
-
- The _H_y_l_a_F_A_X scheduler, _f_a_x_q(1M), uses the information stored
- in this directory when deciding if a call should be placed
- and when preparing documents for transmission. If a remote
- device's capabilities are known, then document preparation
- is constrained and/or optimized according to the
- capabilities. Otherwise, documents are prepared without
- regard for the remote device's capabilities and if a
- capability mismatch is encountered the session is terminated
- and the documents are reformatted using the newly discovered
- capabilities.

- The _c_a_l_l_e_d_B_e_f_o_r_e item is used by _f_a_x_s_e_n_d to decide whether
- or not to redial a phone number when encountering certain
- errors. For example, if a dialing command results in a ``NO
- CARRIER'' result, then the number will not be retried unless
- the number has previously been dialed successfully.
-
- The _m_i_n_S_c_a_n_l_i_n_e_T_i_m_e item indicates the minimum scanline time
- parameter used for facsimile transmissions. Acceptable
- values are: ``0ms'', ``5ms'', ``10ms/5ms'', ``10ms'',
- ``20ms/10ms'', ``20ms'', ``40ms/20ms'', and ``40ms''.
- (Values of the form _X/_Y mean to use _X for 98 lpi images and
- _Y for 196 lpi images.)
-
- The _p_a_g_e_r_T_T_Y_P_a_r_i_t_y item specifies the communication
- parameters to use when communicating with the IXO/TAP
- service provider. Acceptable values are: ``even'' (7 bits,
- even parity), ``odd'' (7 bits, odd parity), and ``none'' (8
- bits, no parity). If nothing is specified then ``even'' is
- used per the standard.
-
- The _p_a_g_e_r_M_a_x_M_s_g_L_e_n_g_t_h, _p_a_g_e_r_P_a_s_s_w_o_r_d, and _p_a_g_e_r_T_T_Y_P_a_r_i_t_y
- items can be setup according to the requirements of a pager
- service provider; they typically are locked down so that
- their values are not lost during updates.
-
- The _p_a_g_e_r_S_e_t_u_p_C_m_d_s can be used to define AT commands for
- setting up the modem for a specific service provider. This
- value overwrites the settings defined in _c_o_n_f_i_g(4F).
-
- The _p_a_g_e_S_o_u_r_c_e parameter can be used to tell the paging
- central who we are. It usually contains a SMS answerable
- mobile number. It is only used for the UCP part of
- _s_e_n_d_p_a_g_e(1M). NNNNooootttteeee:::: This parameter should be used from
- user-land _s_e_n_d_p_a_g_e(1) and will be removed later.
-
- The _p_a_g_i_n_g_P_r_o_t_o_c_o_l defines which protocol, UCP or IXO,
- should be used to send the message to the service provider.
- It defaults to ``ixo''; for UCP set ``ucp''.

- _f_a_x_s_e_n_d, _p_a_g_e_s_e_n_d, and _f_a_x_q automatically create and update
- entries in the iiiinnnnffffoooo directory, as required.
-
- The data in this directory is simply a _c_a_c_h_e of remote
- capabilities and, except for locked down items, can be
- safely purged at any time. The _f_a_x_c_r_o_n(1M) script, for
- example, periodically purges unlocked entries in this
- directory that have not been accessed in 30 days.
