   You are right.  The setport utilities do not work.  No matter how you
set them, you will get a report saying that the aero hardware does not
directly support ECP EPP, but that windows 95 provides software support for
ecp epp.
    Therefore, i think the utilities are not useful, and are deceptive. 
Perhaps they work for other computers in the Compaq line but they do not
work in either of my two aeros, 4/25 and 4/33, nor in mmy son's 
Contura 400. Compaq should get rid of this utility or make it work
properly.
   I removed the setport utilities and go with the flow.  I guess it means
no printing  or file transfer via ECP EPP under ms-dos and Win 3.1, but
only under w95


[C] the following are the EPP files from Compaq:

SP2158.EXE -- 41 K -- (26 September 96)
     Setport is a utility that utilizes the IEEE 1284 BIOS specification to
     configure the parallel port into various modes.<p>

SP1630.EXE -- /pub/softpaq/Software-Solutions/ -- 42 K -- (11 June 96)
     This softpaq contains four versions of EPP BIOS to use in conjunction 
     with EPP aware devices.  Each EPP mode has been known to fix particular
     problems related to these devices (including tape backup systems). 
     EPPBIOS.SYS - standard EPP mode EPPFIFO.SYS - standard EPP mode with
     FIFOs enabled EPPSLCOM.SYS - SL compatible EPP mode 
     EPPSLFIF.SYS - SL compatible EPP mode with FIFOs enabled Only one of 
     the above files should be loaded in your CONFIG.SYS.
     SUPERSEDES: SP1147

sp1147.zip -- 38 K -- (27 February 95)
     EPPBIOS.SYS is a driver which will load IEEE 1284 EPP (Draft Rev. 3) Bios
     Support on Compaq Contura Aero or Contura 400 Family machines. IEEE 1284
     EPP (Draft Rev. 3) Bios support is needed for adapters to use IEEE 1284
     (Draft Rev. 3) specified EPP functions.

sp0937.zip -- 12 K -- (16 September 94)
     EPPBIOS.SYS (Ver. 1.4) is a driver that gives IEEE 1284 EPP BIOS Draft
     Revision 3 Support For Contura Aero and Contura 400 Family. This softpaq
     supercedes sp0935.exe.

sp0935.zip -- 12 K -- (15 September 94)
     EPPBIOS.SYS (Ver. 1.3) gives IEEE 1284 EPP BIOS Draft Revision 3 Support
     for Contura Aero and Contura 400 Family. Supersedes Softpaq sp0889.exe.

sp0889.zip -- 12 K -- (17 August 94)
     EPPBIOS.SYS is a driver which will load IEEE 1284 EPP Bios Support on
     Compaq Contura Aero machines. IEEE 1284 EPP Bios support is needed for
     adapters to use IEEE 1284 specified EPP functions.
