- AOS/VS C-Kermit system requirements and installation instructions are in the
- file CKDKER.INS. Please be sure you have read that file before concluding
- that C-Kermit isn't working correctly on AOS/VS.

- DOCUMENTATION
-
- C-Kermit 5A is documented in the book "Using C-Kermit" by Frank da Cruz
- and Christine M. Gianone, Digital Press, Burlington, MA, USA. Digital
- Press ISBN: 1-55558-108-0; Prentice-Hall ISBN: 0-13-037490-3. Price: US
- $34.95. In USA, call DECdirect at 1-800-344-4825, refer to order number
- EY-J896E-DP.
-
-
- RESTRICTIONS
-
- Commands:
-
- . Local C-Kermit commands such as WHO, DIR, etc, that are implemented through
- CLI calls cannot be interrupted except by entering BREAK (CMD-BRK on DG
- terminals) followed by ^C^A.
-
- . The MAIL command has not been implemented
-
- . The BYE command has not been implemented.
-
- . The WHO command does not accept arguments.
-
- . It is not possible to SUSPEND AOS/VS C-Kermit sessions.
-
- Communications:
-
- . The AOS/VS serial communication device driver requires the RS-232 Carrier
- Detect (CD) signal to be on before it can communicate. For dialout
- connections, therefore, the modem must be configured to force Carrier Detect
- to be on at all times. Direct connections should feed another active
- signal, such as DTR, into the VS system's serial port CD circuit.
-
- . AOS/VS Kermit cannot determine the status of modem signals on a line.
-
- . When a locally-established connection to a remote system has been broken,
- the local AOS/VS C-Kermit will write "Communications disconnect" to the
- screen, but will not finish the rest of the line until there is input from
- the keyboard.
-
- File Transfer:
-
- . The fullscreen file transfer display is not supported.
-
- . If a file is sent to AOS/VS C-Kermit whose name contains VS template
- characters (+, *, ^, \, #), C-Kermit fails to open the output file and
- the transfer fails. (This was fixed 12 May 93 -- "show versions" should
- report "Data General file support, 5A(065) 12 May 93".)
-
- . When AOS/VS C-Kermit is running in server mode, and receives a BYE command,
- AOS/VS C-Kermit terminates but its parent process does not. Thus you must
- still CONNECT back to the AOS/VS system and log out.
-
- . When AOS/VS C-Kermit is receiving a file, and the file collision action is
- set to "update" (meaning that the incoming file should overwrite the
- existing file only if its "creation" date is more recent), and the incoming
- file is in fact newer, the modification date on the resulting file will
- actually be the date/time of the transfer (the real last modification
- date/time). This can cause succeeding "update" operations on this file
- to fail.
-
- . One user reports that in order for AOS/VS C-Kermit to receive 8-bit binary
- files, the CLI command CHAR/ON/8BT must be given before starting C-Kermit.
-
-
- KNOWN PROBLEMS
-
- Abnormal terminations (stack dumps) may occasionally occur on expiration of
- certain timers (when, for instance, the local Kermit gets no response from the
- remote Kermit). Apparently this happens only in local mode, i.e. when
- C-Kermit was used to initiate a connection to another computer by DIALing.
- Cause: Unknown. Cure: Unknown. Possible workarounds: (a) Tell C-Kermit to
- SET SEND TIMEOUT 0; (b) Make your connection without using the DIAL command.
- (These workarounds are untested.)
