Used for User Service PPP or SLIP, determines whether Van Jacobsen

Compression

Compression is used on the link. VJ compression is a means of reducing the

 

standard TCP/IP header from 40 octets to approximately 5 octets. This gives a

 

significant performance improvement, particularly when interactive

 

applications are being used. For example, when the user is typing, a single

 

character can be transmitted and thus have the overhead of the full TCP/IP

 

header. VJ Compression has minimal effect on other types of links, such as ftp,

 

where the packets are much larger. The User VJ Compression option will

 

override the VJ Compression value set for a Serial Port.

 

Default: Disabled
