Lincoln What do you mean no compression? If you are moving text files around, ftp or telnet, then compression can increase throughput by about 10-15%. The only place the compression takes place is between your modem and the host's modem. That way the info can get into the faster transport sooner. Unless of course the host you are talking to also uses slip without compression. Jim -- UUCP: nosc!jadpc!jdeitch ARPA: jadpc!jdeitch@nosc.mil INET: jdeitch@jadpc.cts.com
