Program Thinks
Modem is Online
If you receive an ONLINE message somewhere on your
DTE screen but the modem is not online, set the CXR
command to normal setting using the
AT&C1&Wn<ENTER>
command (and then store this
command into the communications software’s
initialization string field).
Screen Displays
Unusual Characters
If your DTE screen displays unusual characters while
you are off-line, check the speed setting of your
communications software or terminal and the character
length and parity. To match the software settings to the
modem, type A7 <ENTER> and get the OK message
back.
If you are on-line, a common problem involves error
control. If your modem is set for error control but you
did not complete an error control handshake, you can
see a lot of unusual characters on your screen. Force
error control using the
AT\N4<ENTER>
command, then
redial the telephone number.
By forcing error control (\N4), the modem will hang-up
the connection if it doesn't successfully negotiate error
control. If this happens several times, then you must
also reduce the maximum handshake speed using
S37=nn. Try 9600, then try faster speeds to determine
the maximum line speed that you can support on your
telephone line.
If your communications software program does not have
the Zypcom or Cirrus Logic modem listed in its modem
setup menu, and it is possible to define a custom
modem, then type the following initialization string:
