Direct Mode, Flow Control, Protocol Commands | Motorola V.3600

Protocols

Direct Mode

The DTE speed and DCE speed are forced to be the same. No error control or buffering.

Note

In direct mode, with the DCE link established at a rate other than the original DTE speed, the modem issues the connect message for the new DTE speed at the original rate. All subsequent data will be sent to the DTE at the new DCE speed.

Flow Control

If the serial port speed exceeds that of the modem connection, characters may be sent by the DTE to the modem faster than it can send them to the remote modem. The modem holds characters in an internal buffer until they can be transmitted. When this buffer is full, the modem uses flow control to cause the DTE to stop sending characters. As the modem continues to transmit data and the buffer empties, flow control is again used to cause the DTE to resume sending data. The modem can use hardware flow control (RTS/CTS) or in-band flow control (XON/XOFF).

Protocol Commands

These commands enable or control the various data compression, flow control, and error correction options of the modem. Table 6-1 lists the features associated with each mode.
