NOTE 1 — MTDM is being manufacture discontinued.

NOTE 2 — flow control problem. Both the MTDM and the 7400A expect XON/XOFF flow control when
running 19.2 Kbps. Voice messages can emulate XON/XOFF. This results in lost data and dropped
connections.

NOTE 3 — not tested.

NOTE 4 — not tested; expected to fail.

NOTE 5 — not tested; expected to work.

NOTE 6 — 7400A expects a result code that is not given by the modem. 3296 sends a 32 and the 7400A
expects a 12. 3296 sends a 37; 424 sends a 17 for 19200 and the 7400A expects a 14.
