Direct Operating Mode

Configuring the Modem

If you select Mode=Direct (EC/DC OPT’S category):

•Speed conversion and flow control are not supported. If the communications package does not support speed detect, change the 326X’s modulation mode to Auto V.32, and after a connection is established, change the communications software rate to match the modem’s connection rate.

•If the communications package supports data rates higher than 9.6 kbps, set the

modem’s maximum rate (Max Rate, AT*MX) to the higher rate and disable the adaptive rate feature before placing or answering calls. Ensure that the

package’s speed and the modem’s connection rate match when the connection is established. NOTE: Some communications software packages support the automatic speed detect feature, which automatically matches the modem’s baud rate with the software package’s baud rate.

Transferring a File

Refer to the communications package instructions for the procedure for transferring files using the communications software package’s supported protocols.

Ring Messages

Some communications packages wait for ring messages to be received before the modem answers incoming calls. The 326X Series Modem must be set to the communications software package’s baud rate before the package recognizes the ring message. Set DTE Rate, by the front panel or by issuing an AT command, when the modem is configured for autobaud operations.

Flow Control Requirements

•Flow control prevents buffer overflow when line disturbances cause frequent

retransmissions. See “AT*FL” (for the DTE) and “AT*MF” (for the modem) in Appendix A.

If the communications package does not directly support the 326X Series Modem and you want to use the package’s file transfer method:

•If the communications package supports RTS/CTS flow control, enable it:

a)Set the modem to Flow=RTS/CTS

b)Set Modem Flow=Off

c)Transfer data, using the instructions in the communications package.

•If the communications package does not support RTS/CTS flow control:

a)Set the modem to Flow=Off

b)Set Modem Flow=Off

c)Transfer data, using the instructions in the communications package.

•If the communications package supports the automatic speed detect feature, set Max Rate to a value also supported by the software package. Set Speed Conver=Off. Set the modem’s adaptive rate parameter to Off.
