Seconds or
1/100th sec
During synchronous operation with the &Q1 command in effect, S-register S25 is the number of
seconds after a telephone line connection is made before the modem examines DTR. This allows
sufcient time to disconnect the modem from an asynchronous terminal and attach it to a synchronous
terminal. In the On-Line or Command state during any mode of operation, changes in DTR for less
than S25 hundredths of a second are ignored.
