Fax modem needs to work with server under DOS

I have an HP DL140 server and it has DOS 6.22 loaded on it because it needs to run a DOS and Cobol legacy dialer program
The program previously ran on an old HP Vectra VL400 with an internal USR Sportster 14400 ISA modem through a daughterboard. This was one of those old modems that had external DIP switches. However both the Vectra and the ISA modem are now fried and spares almost impossible to get. Well, the Vectra maybe but the modem is pretty much a museum piece.
I have a USR5630D 56K External Faxmodem which is still available and have a com port to run it through on the server (which is around a year old). I have another legacy pc app which uses modern pc's with the an old init string which seems to run with the us robotics dos driver to run the external modem I mentioned above. However, I cannot find anything on the pc which contains the modem init strings as I want to crib these and use them in the server based app to initialise and use the modem in the same way as on the pc. Can anyone tell me the following please

a)what is the correct init string for this modem (cant find it on any sites)
b) is there a way I might be able to test this outside of the legacy app through dos itself to check it works

You can do elementary testing on the modem from the command line like this:
COPY CON COM1
ATD
^Z
That should cause the modem to pick up the phone and give you a dialtone. For anything more elaborate you will probably need a terminal program.

Didn't get to go in the office. In fact, had no time at all to try this out so far this week, but time is getting critical, so will get one of our group to try this out and update here
