Terminal Adapter AT Commands & S-Registers
#Xn Send Single/Multiple Xoff Characters
Values: n = 0 or 1
Default: #X0
Allows the TA to send either a single or multiple Xoff characters to exert
flow control to the terminal. 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)
