Sometimes, a particular Host may have very old V.32 9,600 baud modems that will not train with the newer V.34+ 33,600 bps modem tones. Therefore, it will be necessary to send your modem a special Hayes "AT" command string as shown below to slow your modem up to a lower speed.

Note - this AT option works on;y in the DOS version of 3780, not the Windows 3780 version.

Sample Command (CMD) file (note - don't put a dot "." in front of the ATS37=9:

ATS37=9 [SEE CODES BELOW]

.CALL, 1-XXX-XXX-XXXX

.MESSAGE, [YOUR LOGIN ID AND PASSWORD]

.SEND, SENDFILE

.EXIT

 

Codes for locking-in lower modem speeds:

9,600 = 9

14,400 = 11

19,200 = 11

24,000 = 28

28,800 = 15
