The Kermit Settings - File Transfer General Page

Use the options in the Kermit General page to set up common Kermit file transfer options. Before you can use Kermit for transferring files, you must specify whether the host Kermit is Interactive or Server. If you have already selected Kermit as your File Transfer Protocol, you can access the Kermit General page by choosing Settings from the Options menu. Otherwise, choose Session Type from the Options menu and change your File Transfer Protocol, then choose Settings.

Description

Remote Kermit

Select either Interactive or Server to specify the server type for the remote Kermit.

Interactive

Specifies that the remote Kermit is Interactive (or non-server). An Interactive Kermit must be given commands manually. The Kermit in this emulator is Interactive. If the remote Kermit is also interactive, you must issue complementary commands to each computer to start a file transfer. A Receive command at one computer requires a Send command at the other.

Server

Specifies that the remote Kermit is a Server. A Server Kermit can be completely controlled by an Interactive Kermit. The Kermit in this emulator is Interactive. From your PC, you can control when files are sent and received.

Block Check

Specifies the error detection method to use when sending files to the host. The default is Sum-1. However, if you use large packets (greater than 94 bytes), or the line is noisy, you should use one of the longer checksums, preferably CRC. Not all Kermit implementations support the longer checksums. This Kermit requests to use the selected option, but accepts whatever the receiver replies it wants to use.

Sum-1

Simple one-byte checksum. Supported by all Kermit implementations.

Sum-2

Simple two-byte checksum.

CRC

16-bit Cyclic Redundancy Check using CCITT polynomial. Select this error detection method if you use large packets (greater than 94 bytes) or transfer files over a noisy line.

Rx Packet Length

Type the maximum length (30 - 1024 bytes) for a packet that can be received from the remote Kermit. If you type a value greater than 94 and the remote Kermit does not support long packets, the standard packet size, 94 bytes, is used. The default value is 506.Set this option to a low value if you transfer files over noisy lines.

Tx Packet Max Length

Type the maximum length (30 - 1018 bytes) for a packet that can be sent to the remote Kermit. If you type a value greater than 94 and the remote Kermit does not support long packets, the standard packet size, 94 bytes, is used. This value takes effect only if you set it before Kermit parameter negotiation occurs. The remote Kermit specifies the maximum packet length it can receive. The default is 250.

Set this option to a low value if you transfer files over noisy lines.

Window Request

Type the maximum number (1 - 8) of unacknowledged packets to allow. The default value is 7. The actual number used depends on the negotiation with the remote Kermit. Therefore, a value lower than the one you type in this field could be used.

To set up Kermit file transfers

  1. From the Options menu, choose Session Type.

  2. Under File Transfer Protocol, select Kermit.

  3. Choose Settings to display the Settings dialog box.

  4. In the Kermit General page under Remote Kermit, select Interactive or Server, depending on the mode of your host Kermit.

  5. Select other appropriate options in the General page.

    Because the default options in the Kermit Advanced page conform to the standard Kermit configuration, they are suitable selections for most users, and usually do not need to be changed.

  6. In the File Handling, Folders, and File Types pages, select the options that suit your requirements.

    The Kermit options you set are saved when you save your session and used whenever you use the same session profile.
