Kermit over Serial (RS232)

The Kermit over Serial (RS/232) communication point transfers messages over a serial communication point using the Kermit protocol. Kermit is a file transfer protocol which provides a consistent approach to file transfer, terminal emulation, script programming, and character set conversion across different computer hardware and operating system platforms.

Refer to http://www.columbia.edu/kermit/blank.html for details about the Kermit Protocol.

Refer to Serial Port Problems on UNIX for details about common problems when running serial communication points on Unix.

Serial communication points are only available on Windows and Linux (unavailable on HPUX, Solaris and AIX).

Supported Operational Modes: Input, Output

Input Mode Properties

Property	Description
Port Name	Options: `com3`, `LPT1`, `LPT2` (Windows® environment only) Identifies the name of the port to which to connect.
Baud Rate	Options: `50 - 115200`. Default: `9600` Identifies the speed of the serial connection. Since most devices do not have automatic baud rate detection, you must manually set the baud rate at both ends of the RS-232 connection.
Flow Control	Options: `None`, `RTS/CTS`, `XON/XOFF`. Default: `None` Identifies the flow control mode.
Init Sequence	The sending/expected sequence pairs which will be used for the serial transport initialization before sending the message to the remote host. You should be able to establish serial comms without an initilization seq.
Init Timeout	How long (in milliseconds) to wait for the init sequence to be processed. A value of `0` (zero) means no limit.
Parity	Options: `Even`, `Mark`, `None`, `Odd`, `Space`. Default: `None` Identifies the data parity mode.
Streaming Mode	Options: `True`, `False`. Default: `False` Identifies whether data streaming mode is used or not. Mode is disabled when there is a high level of line noise or high speed transfer is required.
Log Connections	Options: `True`, `False`. Default: `False` If `True`, establishing and dropping of all connections to the communication point are logged to the log file specified in the Connection Log File property. Use of this logging facility slows the communication point down considerably. It is intended for debugging purposes and should not generally be used.
Log Data	Options: `True`, `False`. Default: `False` If `True`, all data passed over the connections of the communication point is logged to the log file. This is potentially a lot of data.
Log Data As Hex	Options: `True`, `False`. Default: `False` If `True`, the hexadecimal representation of the data is logged to the log file. If `False`, the data is logged exactly as it is as it passes over the communication point connection.
Connection Log File	The full file name (path and file name) of the file on the server to which the information is logged.
Extra Information	Options: `None`, `Log Time`. Default: `None` If set to `Log Time`, timestamps are written with each logged event.

Output Filename	The filename given to messages that are sent to the remote host. You can enter any text string as the name to use. Alternatively, the filename can be chosen from the list of the communication point's Published Properties. Refer to File Naming Options, described in General Communication Properties for details.
