S13
Remote Configuration Escape Character
Unit: ASCII Character
Range: 0-127
Default: 37 (%)
Description: S13 defines the remote configuration escape
character (which becomes your modem's remote configuration
character). The default is three percent symbols (%%%). When the S13
character is entered three consecutive times from a remotely connected
site, your modem responds with its Remote Configuration procedure.
S18
Automatic Leased Line Restoral
Unit: 30 minutes
Range: 10-255
Default: 30 minutes
Description: When the MMH2834 is in dial back-up mode, it
periodically checks the lease line to see if it is operational and tries to
restore the lease line if possible. S18 defines how often attempts occur.
The default of S18 is 30 minutes and can be set in one minute
increments from 10 to 255 minutes. Setting the S18 restoral under 10
minutes causes excessive breaks in dial-up operation.
S19
Dial-Back Timer
Unit: 1 minute
Range: 0-255
Default: 1
Description: S19 is a timer that begins when the lease line goes
down. S19 specifies the duration of time the modem attempts to
reestablish the lease line connection.
