NAME

       bpchat - Bundle Protocol chat test program

SYNOPSIS

       bpchat sourceEID destEID [ct]

DESCRIPTION

       bpchat uses Bundle Protocol to send input text in bundles, and display the payload of
       received bundles as output.  It is similar to the talk utility, but operates over the
       Bundle Protocol.  It operates like a combination of the bpsource and bpsink utilities in
       one program (unlike bpsource, bpchat emits bundles with a sourceEID).

       If the sourceEID and destEID are both bpchat applications, then two users can chat with
       each other over the Bundle Protocol: lines that one user types on the keyboard will be
       transported over the network in bundles and displayed on the screen of the other user (and
       the reverse).

       bpchat terminates upon receiving the SIGQUIT signal, i.e., ^C from the keyboard.

EXIT STATUS

       "0" bpchat has terminated normally.  Any problems encountered during operation will be
           noted in the ion.log log file.

       "1" bpchat has terminated due to a BP transmit or reception failure.  Details should be
           noted in the ion.log log file.

OPTIONS

       [ct]
           If the string "ct" is appended as the last argument, then bundles will be sent with
           custody transfer requested.

FILES

       No configuration files are needed.

ENVIRONMENT

       No environment variables apply.

DIAGNOSTICS

       Diagnostic messages produced by bpchat are written to the ION log file ion.log.

       Can't attach to BP.
           bpadmin has not yet initialized Bundle Protocol operations.

       Can't open own endpoint.
           Another application has already opened ownEndpointId.  Terminate that application and
           rerun.

       bpchat bundle reception failed.
           BP system error.  Check for earlier diagnostic messages describing the cause of the
           error; correct problem and rerun.

       No space for ZCO extent.
           ION system error.  Check for earlier diagnostic messages describing the cause of the
           error; correct problem and rerun.

       Can't create ZCO.
           ION system error.  Check for earlier diagnostic messages describing the cause of the
           error; correct problem and rerun.

       bpchat can't send echo bundle.
           BP system error.  Check for earlier diagnostic messages describing the cause of the
           error; correct problem and rerun.
