Programming InterfacePage 334 4This command selects the modem chip set’s DE or port flow control. If the modemchip set is receiving data from the remote modem faster than it can be processed,enabling port flow control allows the modem chip set to handle the data efficiently.\G0 Disable port flow control.\G1 Set port flow control to XON/XOFF flow control.Result Codes:OK n=0,1.Error Otherwise.\Jn Bits/s Rate AdjustThis command allows the modem chip set and the DTE to exchange asynchronousdata up to 57,600 bits/s, regardless of the speed of the data connection between themodem chip set and the remote modem.\J0 Turn off feature.\J1 Turn on feature.Result Codes:OK n=0,1.Error Otherwise.\Kn Set Break ControlThis command selects the way in which the modem handles a break signal. Thismodem chip set can handle a break signal in one of three ways: expedited destructive,expedited, or queued break.(In command state, if reliable mode, then transmit break, to remote)0,1 Destructive/Expedited2,3 Nondestructive/Expedited4,5 Nondestructive/Nonexpedited(In connect state, if direct mode then receive break at serial port)0,2,4 Immediately send break and enter command state1,3,5 Immediately send break through(In connect state, receive break at modem port, send to serial port)0,1 Destructive/Expedited |
