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. Available: January 1993.
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.
. 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 may occasionally occur on expiration of certain timers
(when, for instance, the local Kermit gets no response from the remote
Kermit).
