@
Refresh Abort Character
~~~~~~~~~~~~~
The @ command switches the modem into the abort character receive routine. With
this command, you can change the Control T default abort character into any ASCII
character you like.
The abort character is a software means by which the modem may be disconnected
from the telephones. To program this symbol, press (@). The next key the modem
receives will be stored as the abort character. The type of abort character sent
determines whether it is a displayable code . Therefore , the modem may or may not echo
the selected abort character.
The abort character is shown in the listing in hex code since non-displayable codes are
usually used . The Control T character is shown as ABORT CHAR:l4H in the listing .
Mm
Manual/automatic toggle
The DC-2212 modem, when freshly powered on, defaults to automatic mode operation.
To change to manual mode , toggle the manual/automatic flag by pressing
00
for the
M command. Then press
CD
to see the status of this flag . The list shows MANUAL
M 0 DE : Y:
"Yes, I'm in the Manual mode." Press
00
again and the list changes to
MANUAL M 0 DE : N: "/'
m in the automatic mode." Pressing the key again changes the
parameter setting to manual mode again.
G,g Forced carrier detect tog_g_le
~--"'"'-=~~~~~------~~~~--'
This toggling command controls the carrier detect signal applied to the computer or the
terminal. When freshly powered on, DC-2212 is commanded to force a carrier signal to
your computer. If your computer does not need an asserted carrier to output RS-232
data (some do), you can turn the carrier off by toggling the carrier default.
You can see the action of the G command in two ways. First, watch the modem's front
panel CD indicator go off and on each time you press
CID.
Next, check the parameter
listing for reply line F 0 RC E CARD ET
by using the L command to bring the list to the
screen.
E,e
Echo disable/enable command
~~~~~~~~--'
The E command toggle allows you to defeat or disable the modem's echo and list
ability. Normally defaulted on, DC-2212 echoes displayable characters and generates a
listing when the L command is received. After receiving the E command, the modem
will not echo nor print out its status in response to the L command.
