Link options |
Window |
Only affects UPD/IP connections. The size of the sliding window, in packets. Choices are: |
|
|
Auto |
Your computer will determine the largest possible window size. We recommend this choice unless your connection fits one of the special cases described for the other choices. |
|
|
8 |
Choose this if you are connected over a link with long delays, such as a Wide Area Network (WAN) or satellite link. This choice trades off slower file transfers for better response to commands. |
|
|
16 |
Choose this on medium or slow connections, such as dialup. |
|
|
32 |
Choose this to get the best performance on fast 10MB or 100MB Local Area Networks (LANs). |
|
Packets |
Only affects UPD/IP connections. The maximum packet
size. You may need to set this if you are communicating over multiple network types. Larger packets are more efficient, but will slow down the response to other commands while file transfers are in progress. Packet size choices are: |
|
|
Auto |
We recommend this choice unless your connection fits one of the special cases described for the other choices. |
|
|
232 |
This will improve response to commands at the expense of file and text transfer speed. |
|
|
512 |
Choose this for slower dialup connections to prevent file transfers from slowing down response too much. This is the best choice for dialup IP. |
|
|
1024 |
This is the best choice for maximum file transfer performance on fast 10MB or 100MB networks. |
|
Lock |
Whether to decrease the packet size if transmission errors are encountered. Choices are: |
|
|
None |
Allows FirstClass to change the packet size. We recommend this choice. |
|
|
size |
Locks the packet size at the size you choose. |
|
Encrypt |
Whether to encrypt transmitted data. Note Remember that the level of security you choose will be used by default for all of your settings files which use this connection protocol. If you want to override this default for a particular settings file, update "Encryption" on the Service Setup form. Choices are: |
|
|
Password Only |
Doesn't encrypt data. Suitable for a secure network connection such as one that ties together your system's components when they are on different machines. |
|
|
Secure |
FirstClass standard encryption, which encrypts data at a basic level. This is most frequently used on networks when you want a fast connection and aren't particularly concerned about security. |
|
|
CAST-128 |
CAST-128 encryption, which encrypts data in a more secure manner than Secure. It is equivalent to the security used, for example, when you do banking on the Internet. The first time you log in with CAST-128 encryption, you might find that it takes a little longer than normal to connect. You won't notice this slowdown on subsequent connections. |
Trace options |
The events for which you want trace information. Selecting "Packets sent" or "Packets received" may decrease your link speed significantly, because FirstClass must then write a great deal of data to disk. |
