I've Faxman SDK 4.6.1, I have three fax USB modem (Multimodem MT9234ZBA-USB) successfully detected by Faxman, the problem is when I send three fax in same time it use only one modem to send ! You told me that faxman SDK can choose automaticly the fax port that is free.
I hope that there's a piece of code (c#) to make Faxman SDK sending many fax in the same time by choosing automaticly the fax port that is free, otherwise I will ask for a refund.
FaxMan has a feature that it will only use one modem to send faxes all going to the same fax number, I suspect thats what you are seeing.
If you send the test faxes to different fax numbers you should see all configured modems used to send the faxes.
Also make sure the modems are configured to send, by default they are but its possible to configure ports to be send only, receive only or send and receive.
