Motorola 326X V.34, V.34-SDC Register 25-Delay Before Looking for DTR, Register 26-RTS/CTS Delay

S-Register 25—Delay Before Looking for DTR

Stored in Nonvolatile Memory?: Yes

Status-Only?:No

Default:5

Range: 0 to 255 (seconds)

When DTR Delay=S25 (AT*DT), and AT Form=Sync Data (AT&M) or V25 Form=AsynSync, the modem goes into synchronous data mode after the modem dials asynchronously. S-Register 25 lets you switch from an asynchronous DTE to a synchronous DTE without hanging up. S-Register 25 allows this switch by specifying how many seconds the modem waits after connecting before looking for DTR.

S-Register 26—RTS/CTS Delay

Stored in Nonvolatile Memory?: Yes

Status-Only?:No

Default:1

Range: 0 to 255

This S-Register selects the delay between CTS and RTS while the modem is online. It operates in modes specified by the RTS (AT*RS) and CTS (AT*CT) commands.

The time is selectable in 1/100 second intervals, from 0 to 2.55 seconds.

S-Register 30—DTE Inactivity Disconnect

Stored in Nonvolatile Memory?: Yes

Status-Only?:No

Default:0

Range: 0 to 255 (x 10 seconds)

If DTE Inactivity=S30 (AT*SI), the modem disconnects when data is not sent or received for an amount of time greater than the value stored in S-Register 30, multiplied by 10 seconds. Time-outs range from 10 to 2550 seconds (42.5 minutes). A value of 0 stored in S-Register 30 disables the DTE inactivity option.
