Indicates the minimum number of free modems that must be maintained to handle incoming calls. This parameter allows the Modem Manager to try and keep a free pool of modems available for incoming calls. An outgoing call will be queued while there are less than MinModemsFree modems unused.
Related Variables: If the AnswerCalls variable (see A Config.ini [SYSTEM] Variables) has been set to 0 (false) (as it is by default), then the MinModemsFree variable is ignored.
Default: MinModemsFree = 0
