MODULE KERTRM (IDENT = '3.3.104', ADDRESSING_MODE(EXTERNAL = GENERAL, NONEXTERNAL = GENERAL) ) = BEGIN ! !++ ! FACILITY: ! ! KERMIT-32 terminal processing. ! ! ABSTRACT: ! ! This module will do all of the terminal processing for KERMIT-32. ! It contains the output routines for the terminal to send and ! receive messages as well as the routines to output text for debugging. ! ! ENVIRONMENT: ! ! VAX/VMS user mode. ! ! AUTHOR: Robert C. McQueen, CREATION DATE: 25-March-1983 !-- %SBTTL 'Table of Contents' ! ! TABLE OF CONTENTS: ! %SBTTL 'Revision History' !++ ! ! Start of version 1. 25-March-1983 ! ! 1.0.000 By: Robert C. McQueen On: 25-March-1983 ! Create this module. ! ! 1.1.001 By: W. Hom On: 6-July-83 ! Implement CONNECT command. ! ! 1.1.002 By: Nick Bush On: 7-July-83 ! Fix RECEIVE QIO to time out correctly. ! ! 1.2.003 By: Robert C. McQueen On: 16-Aug-83 ! Get the status correctly for the SS$_TIMEOUT checks. ! ! 1.2.004 By: Robert C. McQueen On: 9-Sept-1983 ! Flag if we just opened the terminal, so that we can ! clear the input that is coming into the terminal. This ! will clear up some of the junk that we get on start up. ! ! 2.0.005 Release VAX/VMS Kermit-32 version 2.0 ! ! 2.0.006 By: Nick Bush On: 10-Nov-1983 ! Fix local echo and IBM mode. ! ! 2.0.013 By: Nick Bush On: 11-Nov-1983 ! Make it possible to redirect debugging output to DBG$OUTPUT. ! ! 2.0.015 By: Nick Bush On: 17-Nov-1983 ! Always purge typeahead when posting the receive QIO. ! Also eat any received data just before sending a packet. ! ! 2.0.020 By: Nick Bush On: 9-Dec-1983 ! Only abort (when remote) if we seen two control-Y's in ! succession. This way a single glitch does not kill us. ! ! 2.0.021 By: Nick Bush On: 12-Dec-1983 ! Add status type-out character (^A), debug toggle ! character (^D), and force timeout character (^M) ! to those accepted during a transfer when we are remote. ! ! 2.0.023 By: Nick Bush On: 16-Dec-1983 ! Add a default terminal name for the communications line. ! If KER$COMM is defined, that will be the default. ! ! 2.0.027 By: Nick Bush On: 20-Jan-1983 ! Fix reset of parity to use the correct field in the ! IO status block from the IO$_SENSEMODE. It was using ! the LF fill count instead. ! ! 2.0.031 By: Nick Bush On: 4-Feb-1983 ! Change connect code to improve response (hopefully ! without worsening throughput or runtime requirements). ! When either terminal is idle we will be waiting for ! a single character with a larger buffered read queued ! up immediately after it. ! ! 2.0.033 By: Nick Bush On: 6-March-1984 ! Change command input and terminal processing so that ! we will always have SYS$OUTPUT and SYS$COMMAND open ! when they are terminals, and will also always have ! the transfer terminal line open. This makes it ! unnecessary for the user to allocate a dialup line ! in order to go between CONNECT and a transfer command, ! and keep anyone else from grabbing the line between ! commands. ! Also add the command parsing for the rest of the LOCAL/REMOTE ! commands. This makes use of the fact that we have ! SYS$COMMAND open to allow us to read passwords without echo. ! Commands which should only be done when Kermit is local ! (GET, BYE, etc.) will now give an error if the transfer ! line is the same as the controlling terminal. ! SEND will now check for the files existance before calling ! KERMSG to send it. ! ! 2.0.034 By: Nick Bush On: 7-March-1984 ! Default the parity type to be that of the default transfer ! line. This should make things simpler for systems which use ! parity by default. ! ! 2.0.035 By: Nick Bush On: 8-March-1984 ! Add LOG SESSION command to set a log file for CONNECT. ! While we are doing so, clean up the command parsing a little ! so that we don't have as many COPY_xxx routines. ! ! 2.0.036 By: Robert C. McQueen On: 20-March-1984 ! Fix call to LOG_OPEN to make the debug log file work. ! Module: KERTRM ! ! 2.0.037 By: Robert C. McQueen On: 20-March-1984 ! Fix call to LOG_OPEN for debug log file. ! Module: KERTRM. ! ! 2.0.042 By: Nick Bush On: 26-March-1984 ! Fix connect processing to make it easy to type messages ! on the user's terminal while connected. Use this ! to type messages when log file stopped and started. ! Include the node name in the messages to keep ! users who are running through multiple Kermit's from ! getting confused. ! ! 2.0.043 By: Nick Bush On: 28-March-1984 ! Fix SET PARITY ODD to work. Somehow, the table entry ! had PR_NONE instead of PR_ODD. Also add status type ! out and help message to connect command. ! ! 3.0.045 Start of version 3. ! ! 3.0.046 By: Nick Bush On: 29-March-1984 ! Fix debugging log file to correctly set/clear file open ! flag. Also make log files default to .LOG. ! ! 3.1.054 By: Nick Bush On: 13-July-1984 ! Change TERM_OPEN to take an argument which determines ! whether it should post any QIO's. This makes it unnecessary ! for TERM_CONNECT to cancel the QIO's, and avoids problems ! with DECnet remote terminals. ! ! 3.1.060 By: Nick Bush On: 16-March-1985 ! Increase size of terminal name buffers to account for large ! unit numbers (most likely seen with VTA's). ! ! 3.1.061 By: Nick Bush On: 16-March-1985 ! Only attempt to set parity back when closing terminal. ! ! 3.1.065 By: Nick Bush On: 10-April-1985 ! Split IBM handshaking from parity and local echo. Allow ! link time setting of IBM_MODE defaults by defining symbols: ! ! IBM_MODE_CHARACTER = character value of handshake character ! IBM_MODE_ECHO = 1 for local echo, 2 for no local echo ! IBM_MODE_PARITY = (0 = none), (1 = mark), (2 = even), ! (3 = odd), (4 = space). ! ! If not specified, Kermit will continue to use DC1, local echo ! and odd parity for IBM_MODE. ! ! ! Start of version 3.2 on 8-May-1985 ! ! 3.2.073 By: Robert McQueen On: 11-March-1985 ! Fix a problem restoring the terminal characteristics under ! VMS 4.x ! ! 3.2.100 By: Gregory P. Welsh On: 1-June-1986 ! Added code for Transmit function (COMND_TRANSMIT). ! ! Start of version 3.3 ! ! 3.3.101 By: Robert McQueen On: 2-July-1986 ! Change $TRNLOG system service to be LIB$SYS_TRNLOG and ! handle the errors better. (LIB$ shouldn't change even if the ! system service does). ! ! 3.3.102 By: Robert McQueen On: 5-July-1986 ! Add changes/fixes suggested by Art Guion and David Deley. ! - Turn off FALLBACK terminal characteristics for eightbit ! operations. ! - Decrease IBM timeouts when waiting for a handshake. ! ! 3.3.105 By: Robert McQueen On: 8-July-1986 ! Attempt to fix the truncation errors that we now get from ! LINK with BLISS-32 v4.2. Also do code clean up in VMSTRM and ! VMSFIL. !-- %SBTTL 'Library files' ! ! INCLUDE FILES: ! ! !
