We are using OpenAT 2.10, Q2406B module.
According to the <<Open At 2.10 Development Guide>>
It is too small! The problem appear when some device does not support Flow Control. Some data just lost.
In our case it is nesessary to encode data from V24, ( 3DES, it is about 16 Kb per second). And during this time V24 buffer overflow.
How can I change V24 buffer size? Any changes in OpenAT 3.x?
