Is it possible to disable hardware echo cancel on one of the 4 ports of a Sangoma A104? I have that port connected to an Adtran 614 used for faxing. Faxing is not working well.

It would depend on how you have dahdi configured, but on my system running a Sangoma B600 card w/ hwec I have these lines in /etc/dahdi/system.conf:

Sangoma AFT-600 [slot:4 bus:3 span:1]
fxsks=1
echocanceller=hwec,1
fxsks=2
echocanceller=hwec,2
fxsks=3
echocanceller=hwec,3
fxsks=4
echocanceller=hwec,4
fxoks=5
echocanceller=hwec,5

IIRC you set the echocanceller=none to disable, but my quick googlefu can’t confirm that.
