modem, it does not
generally configure the
connection speed
between modems!
Press OK once the Bits per
second is configured.
You will advance to the

Use the ATE1 and ATDT
commands to check the
modem connection and
dial the modem. After
issuing the ATE1<ENTER>
command the modem
should respond with OK.
Follow the ATDT
command with the phone
number to dial, then press
<ENTER>. You should
hear the modem dialing the phone number, the carrier detect of the answering modem, and negotiation
for the communications. After successful negotiation the CONNECT response, with baud rate, is issued.
The example shows a successful connection at 1200bps. This string is then entered in the
ModemCallBack instruction.
For example, the ModemCallBack instruction would be modified as follows to match the testing illustrated:
ModemCallBack(CallBackStatus,ComRS232,-2400,0,"5269004","CONNECT 1200",60,120,CallBackAbort)
