I posted a note on my experiences with getting win3 to work with Com3 and Com4.
Basically, you need the following steps:

 a) Use the 34install program (I hope there's only one we are all talking
    about) so that the net effect of running this program is to put the
    address of com3 and com4 into locations 40:4 and 40:6. There seem to
    be a few popular addresses - com3 = 3e8h and com4 = 2e8h (which are
    not the Windows default) worked for me.

 b) Modify your system.ini to include the lines
      Com3Base=3e8h
   Com4Base=2e8h
    (using the addresses used with 34install, obviously)

 c) Look in your win.ini file. If you had a modem when you setup windows, you
    will find a line like Modem=ComX,T,3. Modify X so that it is the com port
    on which you have the modem.

I also started compiling a list of com address pairs that people reported had
worked. In my infinite wisdom, I ended up deleteing the file. Last it had were
three pairs of com4/3 addresses.

Hope this helps.
