Minimum Speed (doModemMinSpeed)
This setting determines the slowest data rate that will be negotiated.
Guard Tone (doModemGuardTone)
Normally a guard tone is not required. But, one can be inserted. This operates for Phase Shift Key modulations
only.
• toneNone(1)
• tone1800(3)
Carrier Loss Duration (doModemCarrierLossDuration)
The number of seconds the carrier must be lost before the connection is determined to have been lost. A set-
ting above 25 indicates forever.
Retrain (doModemRetrain)
Enables the modem to monitor the line quality and request a fallback or retrain for poor quality and a fall for-
ward for good quality.
• none(0)—Do not allow modem to retrain, fallback, or fall forward
• retrain(1)—Allow the modem to retrain if the line quality is poor
• fallForwardFallBack(2)—Allow the modem to fallback to a slower speed if the line quality is poor, of fall
forward to a faster speed if the line quality is good
Tx Level (doModemTxLevel)
Not currently implemented.
Protocol (doModemProtocol)
Assigns the data error correction protocol to use with the modem. The following options are available:
• Direct(0)—No compression will be used.
• requestV42(1)—Enable V.42 compression. If this is selected, the modem will either negotiate for V.42 data
compression or—if V.42 compression is not available—will use no data compression.
• requireV42(2)—V.42 data compression is mandatory, otherwise disconnect.
Compression (doModemCompression)
Assigns the data compression protocol to use with the modem. This setting is in effect only when V.42bis error
correction (see
“Protocol (doModemProtocol)”) is active.
• Direct(0)—No compression will be used.
• requestV42bis(1)—Enable V.42bis compression. If this is selected, the modem will either negotiate for
V.42bis data compression or—if V.42bis compression is not available—will use no data compression.
• requireV42bis(2)—V.42bis data compression is mandatory, otherwise disconnect.
• V44(3)—allows V.44 and V.42bis data compression.
