I have a problem and I hope someone can help me.

I have a DEC3100 running Ultrix V2.0 (Rev. 7)
and am trying to connect to an InterPro 32C (sysV w/berkely extensions)
on a different subnet using ftp.

So far I just get 'Host is unreachable' errors.  Because they
are on different subnets!  I know that.  But I want the 3100
to 'realize' that that are really on the same wire.

ifconfig on the 3100 produces:
    se0:            129.135.200.186
    netmask         ffffff00  (255.255.255.0)
    flags=0x443     DYNPROTO,RUNNING,BROADCAST,UP
    broadcast       129.135.200.255

and the 32C is:
    Internet Address: 129.135.252.150
    Subnet Mask: 255.255.255.0 (ffffff00)

The 32C has a '/etc/gateways' file that is supposed to
make subnets look alike to the machine.  I can't find the equivalent
on the 3100.  I know that I could change the addresses of both machines
but the use of this machine necessitates that I not do that.

If anyone out there knows the magic command line or config file,
I surely would appreciate any help that I can get.  
Meanwhile I will keep RTFM-ing.

Thanks in advance,
