[efax-users] How to use Class1 modem for receiver

[Tomoo Nomura <nomurat@xxxxxxxxx>]

Hello,

It is very difficult to get Class 2 fax modem. All V.90/K56flex modems
support only class 1.
I tried to use one of these, TCtel HSP56 MicroModem, with Linux Driver
K2.4.7.V92.001, and I could send a fax normally but it encountered an
error while receiving a fax.

Here is the log;

Or is there any recommended class1 WinModem ?
