Never heard of any such thing on any modem. Do you happen to have anything
like a reference, on *any* modem, as an example?
[Both my modems (Sound Modem and Express Fax Modem) support Hayes command set
variants returning "result codes," such as, "NO CARRIER", "NO DIAL TONE" or
"CONNECT 14400." They can be configured to give additional result codes for
protocol, e.g., are we using LAPM or V.42bis. This kind of stuff may be
helpful in debugging modem connectivity as might loopback testing. However, I
don't see any documented way to figure out if data is being sent or received,
although maybe that's buried in bit mapped registers somewhere.]
