Worth Data TriCoder t53 User Manual page 231

• The dialing string is typically ATDTnnnnnnnn, where n is any other
modem commands and the phone number you are dialing. One
command you may find useful is a "pause" in the dialing string. A ½
second pause can be inserted by putting a "~" in the dialing string.
Any Hayes-compatible commands can be programmed, but the
length of the entire string must be limited to 24 characters.
• Automatically, the TriCoder resets the modem before the first dialing
attempt and between dialing attempts. You can vary the length of the
delay between dialing attempts (Retry Delay) from the standard
default of 30 seconds to anything from 01-99 seconds. You cannot
make this change by scanning the bar coded TriCoder setup menu; it
can only be made through the keyboard setup on the TriCoder.
Dialing the host...
After setting the TriCoder to the correct protocol (Polled with ACK/NAK or
XMODEM), and specifying the Dialing String, return to the Mode Menu
and answer NO to the prompts until you see:
•
Press the TriCoders "F2" key (not the "Yes" key) to start the
transmission of the Dialing String to the Modem.
•
The TriCoder first transmits the dialing string, then waits for
the modem to answer. If the modem answers, it responds by
transmitting a CONNECT message which the TriCoder
displays on its screen. Because the CONNECT message comes
so fast, some of the characters in the word CONNECT may be
missing on the TriCoder display.
•
If the TriCoder is unable to make a connection on the first try, it
attempts to connect by redialing two more times. The TriCoder
uses the Retry Delay setup in the TriCoder to determine how
long to wait before it tries to dial again. If you do not want the
TriCoder to redial, simply turn the TriCoder OFF. If the
TriCoder is still unable to connect after three attempts, it
displays the following message :
XMODEM Upload
XMODEM is by far the modem protocol of choice. It is available in most
communications software packages, many of which do not require
extensive programming by the user. You can also use XMODEM to upload
by cable without a modem attached, simply by not specifying a dialing
string in the setup. The TriCoder does not try to dial; it just waits to be
