I run DOS 3.3.  I did not need to run any such program.  It might be
necessary in early version of DOS but 3.3 has COM3 and COM4.

It is NOT NOT NOT the address used with the 34install.  It is the address
that your modem is looking for.  If you do need 34install, enter the addresses
that your modem documentation gives.

BTW, this step (modifying Com3Base) was the critical one for my getting
the modem to work.

On my system it was already Com3.  The problem was the ",T,3" was
missing.

This line is in the [Terminal] section of WIN.INI.

Good luck.
