We don't really have any SCO experts and I'm not sure what to tell you. But here are a few thoughts.

First check the local lan as SCO sees it. Try "netstat -i" at least and look for excessive errors or collisions. The box needs a good connection to the lan. Things may have been reconfigured that caused a problem. Also sco may have some addition stats that can be displayed by an additional command. Look for anything like that. And check the traffic flow to/from the box. If the box is doing 15 other concurrent ftp jobs, your job is going to be slow.

Still got a problem? Unplug the sco box for a while and take your pc over and plug in into the sco's network connection. Reset your pc to sco's ip address. Send the file. If it's fast from your pc and slow from the sco, you know that the problem is on the sco. If the pc is also slow, there must be a network issue near the sco.

If the problem is on the sco box, make sure that your os is up-to-date. No fair comparing a 15 year old unix to a recent pc. And make sure that your os has all networking patches. Look around on the sco and see if you can find any way to tune tcp/ip. For example, sun and hp have ndd which can do that.

That's about all I can think of. If you get it working faster, let us know what the problem was.

atmaddr

ATMADDR(8)						       Maintenance Commands							ATMADDR(8)

NAME

       atmaddr - list and maintain local ATM addresses

SYNOPSIS

       atmaddr [-n] [itf]
       atmaddr -r [itf]
       atmaddr -a [itf] atm_addr
       atmaddr -d [itf] atm_addr
       atmaddr -V

DESCRIPTION

       atmaddr	is  used  to list the local addresses configured for ATM interfaces and to manually change the list of addresses. If the interface
       number itf is omitted, interface 0 is used by default. The ATM address atm_addr can be any valid ATM SVC address, e.g. an E.164 address	or
       an ATM Forum NSAP address.

       If invoked without options, atmaddr lists the addresses that are currently configured on the specified interface.

       Note that local ATM addresses are normally automatically maintained by the ILMI demon.

OPTIONS

       -a     append the specified address at the end of the list.

       -d     delete the specified address from the list.

       -n     numeric address output only. No address to name translation is attempted.

       -r     reset (clear) the local address list of the specified interface.

       -V     print the version number of atmaddr on standard output and exit.
