T
erminal Adapter
&E5
XON/XOFF flow control. This is an in-band method, where the XON and
XOFF characters (^Q and ^S, respectively) are inserted into the data stream,
rather than using separate control lines. When an XOFF character is
detected, the data stream is suspended until an XON character is detected.
The drawback to this method is that some files may contain these characters,
causing the file transfer to be suspended indefinitely.
&E6
When XON/XOFF pacing is active, the TA responds to and discards the XON/
XOFF characters from the computer.
&E7 When XON/XOFF pacing is active, the TA responds to the XON/XOFF
characters and passes them through the communications link to the remote
device, thereby pacing the remote terminal adapter as well.
&E12 Disables pacing
&E13 Enables pacing.
#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 = 0-3
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. (See Appendix A.)
&F0
Profile 0 — Modem-like operation (default)
&F2 Profile 1 — V.120 async operation
&F4 Profile 3 — PPP async operation
