The #X0 command (factory default setting) causes one Xoff to be sent until the TA‘s buffer reaches the Xon level. The #X1 command causes an Xoff to be sent for every character received after the TA reaches its buffer full level.

#X0 One Xoff character sent until the buffer reaches the Xon level (default)

#X1 Multiple Xoff characters sent for every character received after buffer reaches the full level.

&Fn Load Quick Setup Profile

Values: n = 0-4

Default: &F0

For quick setup, the TA includes Quick Setup Profiles. Each contains configuration parameters for a specific type of port operation. To load a Quick Setup Profile into active memory use the command &Fn, where n is the number of the profile you want to load. You then can customize the profile and store it with the &W command, so it loads automatically on power-up or reset. These profiles are stored in permanent memory and are not user-configurable.

&F0 Profile 0 — Modem-like async 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 — PPP async operation
