Cabletron Systems CSMIM-T1 manual S25=n Delay to DTR and Asynchronous Time Delay

Chapter 7: AT Commands and Registers

NOTE

If you use register S23 to change the parity set automatically or set by -On, the same number of data and stop bits used before the change is retained. For example, if 8 data bits and even parity is set (-O6) and you change register S23 to odd parity, the 8 data bits and 1 parity bit are retained. However, the parity becomes odd instead of even, changing the Serial-Port Parity command setting to -O5.

S25=n Delay to DTR and Asynchronous Time Delay

Range: Delay to DTR: 0 - 255 hundredths of a second Async mode: 0 - 255 seconds

Default: Delay to DTR: 5 hundredths of a second (0.05 seconds) Async mode: 5 seconds and 0.05 seconds

Delay to DTR: During asynchronous mode with &M2 or &M3 set, the modem ignores an On-to-Off transition of DTR that is less than the register S25 time delay.

Asynchronous time delay: Register S25 sets the number of seconds the modem waits to check DTR after establishing a connection. After this time delay, the Delay to DTR time delay described above takes effect when loss of DTR occurs.
