  41. // 8. ENPREFIX added, extracted from BUFILL
  42. // 9. DEPREFIX added, extracted from BUFEMP
  43. //10. LEN in SFILE replaced by LF (bug) in error messages.
  44. //11. DEPREFIX added to Server_control for R filename packets.
  45. //11A.Prefixing 8 bit quoting now handled if been agreed, not only if Binfile.
  46. //12. Repeat count prefixing added.
  47. //13. Rtypecheck added to allow GEC version of Rfile to compile.
  48. //14. Sfile now does filename conversion to normalform on option .
  49. //15. Hashfile(Rfile) now does filename conversion to normalform on option.
  50. //16. Shower now displays Off/On instead of 1/0.

  55. //21. RECEIVE modified to allow one parameter to specify a receive filename.
  56. //22. If WITH stream specified in process call then take commands from file.
  57. //
  58. // Mods for 3.1
  59. //
  60. // 1. Generic logout included to stop Kermit but no logout, + error message.
  61. // 2. Other Generic commands generate error condition.
  62. // 3. I packets get error message only if quoting not agreed in Binary mode.
  63. //
  64. // Mods for 3.2
  65. //
  66. // 1. /!GEC/! version failed if timeout, fixed.
  67. //
  68. // Mods for 3.3
  69. //
  70. // 1. RPAR changed to handle 'Y' in incoming init QBIN parameter correctly.
  71. // 2. DE_PREFIX comment altered and EN_PREFIX changed to do 11A above correctly
  72. //
  73. // Mods for 3.4
  74. //
  75. // 1. LAST_RETRY added to RPACK to allow checking for a change of reason for
  76. //    retry, in which case the NUMTRY count must be reset. Formerly, five
  77. //    timeouts followed by six checksum errors would have exceeded the limit.
  78. // 2. SET SIZE added to allow changing RPSIZ for protocol variants.
  79. //
  80. // Mods for 3.5
  81. //
  82. // 1. MAXL is redefined by F DE CRUZ as max Len instead of max packet size.
  83. //    Therefore SPSIZ and RPSIZ go down by 2. Alter RPAR and Buffil. Removed
  84. //    the extra character margin from the check, SPSIZ-8 +2 +1 is SPSIZ-5.
  85. //    But also there is a bug in that loop can continue to 5 more chars, not
  86. //    3, so we get SPSIZ-7.
  87. //
  88. // Mods for 3.6
  89. //    Version 3.6 was produced by G Sands, Marconi for Physical mode.
  90. //
  91. // 1. File transfer is done with the terminal in physical mode. This takes
  92. //    care of ?s,linelength restrictions and echo suppression. Also there is a
  93. //    very handy "PUT followed by a timed-out GET" construction. This is used
  94. //    whenever a response is expected to a packet being sent. It is also used,
  95. //    with an empty PUT, when awaiting an initial packet from the other end.
  96. //    This construction has the advantage that the GET is cancelled if it is
  97. //    timed out.
  98. // 2. "Reset terminal to default" instruction is followed by "set backspace=?C".
  99. // 3. /Z... has been added to &KERMLOG, to avoid long transfers crashing when
  100. //    debug is on.
  101. // 4. RPSIZ and limit on SPSIZ in RPAR increased to 94.
  102. // 5. Since the PUT-GET time limit is in seconds not millis and is specified in
  103. //    RX, TIMEOUTs are in seconds and are HALFs (DELAY remains in millis.).
  104. //    Timeout is set only when entering physical mode or when changed, not at
  105. //    each GET.
  106. // 6. HELP SET refers to &KERMLOG not .KERMLOG.
  107. // 7. If receiving and get packet N-1, ack N-1 not N.
  108. // 8. "Now type local ..." added to RECEIVE and SEND.
  109. // 9. Data management errors on send or recieve files are reported - not fatal.
  110. //
  111. //    Routines altered:
  112. //      NEXTC           new buffer is got with a PUT-GET with an empty PUT,
  113. //                      Tests SPACK_TIMEOUT before anything else.
  114. //      RPACK           reset changed for physical after ^Z. 3 ll after =>NUM,
  115. //                      (0) added after RETURN.
  116. //      SPACK           if LISTEN=1, does a PUT-GET. If data recieved, sets
  117. //                      POINTER for NEXTC to return 1st chara in buffer. Resets
  118. //                      LISTEN to 1 on exit. If timeout, flags to NEXTC.
  119. //      RPAR            limit on SPSIZ is 94. TIMEOUT in secs.
  120. //      ERROR           0=>LISTEN before SPACK
  121. //      RTYPECHECK      OPEN options changed.
  122. //      RFILE           0=>LISTEN before ack-ing 'B' packet. If get packet
  123. //                      N-1 ack that not N.
  124. //      RDATA           ack N-1 not N. Trap 'A' from BUFEMP. Trap DMAN error on
  125. //                      PUT.
  126. //      DE_PREFIX       Bug fix as mentioned in 00MAIL90.
  127. //      BUFEMP          Trap DMAN error on PUT.
  128. //      SFILE           OPEN options changed. Trap 'A' from BUFILL.
  129. //      GETC            Trap DMAN error and return -2 on GET.
  130. //      BUFILL          Trap -2 from GETC, pass on.
  131. //      SDATA           Trap 'A' from BUFILL.
  132. //      DEBRIEF         PUT to INSTREAM not OUTSTREAM, follow with CRLF (both
  133. //                      due to physical mode). WAIT removed.
  134. //      SERVER_CONTROL  initialisation changed for physical mode. Return to
  135. //                      logical before resetting terminal. 0=>LISTEN before
  136. //                      ack-ing 'F'. Set timeout when changed.
  137. //      PARSER          TIMEOUT in secs.
  138. //      MAIN            transfer initialisation changed for physical mode and
  139. //                      timeout set. Return to logical before resetting
  140. //                      terminal. IF REMOTE and RFLG or SFLAG output
  141. //                      "Now type local ... ".
  142. //
  143. //
  144. // Mods for 3.7
  145. //
  146. // 1. DE_PREFIX last line, save of ra to databuf included to correct
  147. //    bug causing only first decoded repeated char to be correct.
  148. // 2. EN_PREFIX test in first line changed to test for state S, this
  149. //    caused repeating to not be done on first packet from file.
  150. // 3. EN_PREFIX and GETC heavily hacked to get repeat count prefixing
  151. //    to work properly on Binary file transfers, particularly when
  152. //    2-3 reps were found at the end of a record.
  153. // 4. RDATA AND RFILE altered so that acks for previous packets received
  154. //    again are correctly numbered with the previous packet number. This
  155. //    fix includes correcting the packet length of the first ack in RDATA
  156. //    to zero.
  157. // 5. Length of INBUF extended so that GETC can read records up to
  158. //    1024 in length.
  159. // 6. Attributes Z(1,1,127) added to Kermlog open to provide larger
  160. //    extension.
  161. // 7. Missing RETURN with RA set to zero corrected in RPACK
  162. //    (after 'TYPE' decoded)
  163. // 8. Comments relating to NUM and N corrected.
  164. //
  165. // Mods for 3.8
  166. // 1. Version 3.6 for tf/tc merged with version 3.7
  167. // 2. Generic command 'T' added for remote typing of file.
  168. //
  169. // Mods for 3.9
  170. //
  171. // 1. Test for EOF added in EN_PREFIX (otherwise if last chara. of file is a
  172. //    null get infinite loop).
  173. // 2. In GETC, extra trap on BINEOF. Otherwise infinite loop if file ends with
  174. //    same chara. repeated 2 or 3 times.
  175. // 3. Trap ctrlZ throughout RPACK. Trap premature CR & packet not being followed
  176. //    by CR - treat as checksum error.
  177. // 4. ROUTINE CLOSEDOWN added, principally to avoid displacement errors.
  178. // 5. Version 3.6 mods reintroduced in PRRA, DEBRIEF, RDATA, BUFEMP and
  179. //    SERVER_CONTROL.
  180. // 6. Minor bug fixes to GETC, SEOF, BUFEMP and BUFILL.
  181. // 7. Repeat CONTROLs if timeout. If parity not stripped, mask whole buffer in
  182. //    one go.
  183. // 8. If nothing to do, exit before going physical.
  184. // 9. Prevent normalised name starting with a digit.
  185. // 10. If RECEIVE <filename>, ensure group doesn't go to same file.
