Command: &Fn

Function: Load Quick Setup Profile

Values: n = 0–4

Default: &F0

Description: For quick setup, the TA includes six Quick Setup Profiles, each contains configuration parameters for a specific type of port operation. To load a Quick Setup Profile into active memory, use &Fn, where n is the profile number to load. You then can customize the profile and store it using the &W command, so it loads automatically on power-up or reset. These profiles are stored in permanent memory and are not user configurable. (Appendix B.) &F0 Profile 0 — Modem-like operation (default)

&F1 Profile 1 — V.110 async operation* &F2 Profile 2 — V.120 async operation &F3 Profile 3 — X.75 async operation &F4 Profile 4 — MLPPP async operation

*The MTA128ST-USB is manufactured in two builds. To determine the build of your terminal adapter (TA), issue the ATI2 command in a terminal window. If the TA responds to the command with MTA128ST- USB, then it supports V.110. If your TA resonds to the ATI2 command with MTA128ST-USB-RC, V.110 support is not available. The MTA128ST-USB-RC will respond to the &F1 command with an ERROR..

Command:

&Jn

Function:

Automatic Channel Bundling

Values:

n = 0 or 1

Default:

n/a

Description:&J1 causes the TA to dial the number given in the dial string again to set up

 

a bundled PPP connection (also known as MultiLink PPP). Only works with

 

the PPP/ML-PPP protocol (!Z=9). &J0 will not dial the given number again

 

and it will not interfere with the given dial string meaning that if there are two

 

numbers in the dial string (like ATD5551000&5553000) the TA will dial both

 

of those numbers. &J0 does not disable the dialing of a second number if a

 

second number is given in the dial string.

 

n=0

disables automatic channel bundling

 

n=1

enables automatic channel bundling

Command: &Rn

 

Function:

CTS Control

Values:

n = 0, 1, or 2

Default:

&R1 (CTS forced high)

Description:Allows you control the state of the CTS (Clear to Send) signal on the

 

RS232E/V.24 interface. Normally the CTS signal follows the state of the RTS

 

signal when the MTA128ST-USB is online.

 

&R0 CTS acts normally; i.e., it follows RTS

 

&R1 CTS is forced high, but still provides online flow control

 

&R2 CTS is forced high, but it drops on disconnect for the period of time

 

set by S10. CTS still provides flow control when the TA is online.

Command: &Sn

 

Function:

DSR Control

Values:

n = 0, 1, or 2

Default:

&S0 (DSR high)
