Step 2 - Configure AS/400 For Your Modem
Check to see if a sample configuration exists for your modem. Type CFGTCPPTP,
then select option 11 to view the default modem entries on AS/400. If your modem
is listed, go on to the next configuration step. If your modem is not listed, you can
do either of the following:
v Try the $generic hayes modem entry.
v Add an entry for your modem.
To determine which option is best, check the user manual for your modem. Look for
the following settings for command strings:
v Modem reset to factory defaults: This is often AT&F or AT&Z
v Modem initialization – Some of the options you should set are as follows:
– Display Verbal Result Codes: Often this is Q0 and V1
– Normal CD and DTR modes: Often this is &C1 and &D2
– Echo mode off: Often this is E0
– Data Set Ready (DSR) to follow Carrier Detect: Often, this is &S1
– Enable hardware flow control (RTS/CST)
– Enable error correction and optionally, compression
– Ensure DTE-DCE line speed is enabled to run at fixed 19.2K
– If the modem supports it, optionally enable the inactivity timer
v Modem answer mode:
– Answer after n rings: Often this option is S0=n
– Disconnect if no carrier (connection) after m seconds: Often this option is S7=m
v Modem dial type: This is usually ATDT, which selects tone dialing. To compare,
ATDP selects pulse dialing.
