U.S. Robotics I-modem Command Reference

Appendix A: Alphabetic Command Summary • Page A-36

7 128 Custom applications only.

*The default 1.5K byte non-ARQ buffer allows data transfer with X- and YI-

modem-type File Transfer Protocols without using ßow control.

The 128-byte option allows remote users with slower modems to stop your

transmitted data from scrolling off their screens. When remote users send

your computer an XOFF (<Ctrl-S>) and you stop transmitting, the data in

transit doesn't exceed the size of their screen.

S16 0 Bit-mapped register. (See Chapter 1, Using the A

T Command Set, for

instructions on setting bit-mapped registers.) For testing, see Chapter 14,

Testing.

2 4 Test pattern.

3 8 Remote digital loopback.

S18 0 Test timer for software-initiated loopback testing (&Tn); disabled when S18

is set to 0. Used to set the duration of testing, in seconds, before the I-

modem automatically times out and terminates the test.

S19 0 Sets the duration, in minutes, for the Inactivity Timer. The timer activates

when there is no data activity on the phone line, and at the timeout the I-

modem hangs up. S19=0 disables the timer.
