Hi,
it could still be a modulation related issue.
Since the license is now installed, you should be able to test each of
the following init. strings, one at a time:
---
AT &F W1 +ER=1; +DR=1; +MS=V92,0
AT &F W1 +ER=1; +DR=1; +MS=V92,1
AT &F W1 +ER=1; +DR=1; +MS=V90,0
AT &F W1 +ER=1; +DR=1; +MS=V90,1
AT &F W1 +ER=1; +DR=1; +MS=V34,0
AT &F W1 +ER=1; +DR=1; +MS=V34,1
AT &F W1 +ER=1; +DR=1; +MS=V32B,0
AT &F W1 +ER=1; +DR=1; +MS=V32B,1
AT &F W1 +ER=1; +DR=1; +MS=V32,0
AT &F W1 +ER=1; +DR=1; +MS=V32,1
---
Hopefully one of them will solve the problem.
