Setting data-transmission parameters
1. On the modem-administration form, set the Data Bits: field to 8 (the
default).
2. Set the Parity: field to none (the default).
3. Set the RTS/CTS Enabled: field to &H1 (unless you have an Intel modem,
in which case set it to \Q3).
This enables flow-control.
4. Set the Asynchronous Data Mode: field to &M0, the default (unless you
have an Intel modem, in which case set it to \J1).
5. Set the DTE Auto-Data Speed: field to S90=1 (unless you have an Intel
modem, in which case set it to &M0&Q0).
This lets the modem automatically adjust the data speed to match the
requirements of the remote equipment.
6. Set the Disable Data Compression: field to %C0 (unless you have an
Intel modem, in which case set it to H0%C0, or a U.S. Robotics 839, in
which case the option is not available).
This disables V.42bis and MNP Class-5 data compression.
7. Set the Enable Error Control: field to \N5 (unless you have an Intel
modem, in which case set it to \N3).
This enables LAPM and MNP error control.
Setting dialing parameters
1. Set the Auto-Answer Ring Number: field to S0=10.
This specifies the number of rings that the modem waits before answering
an incoming call.
2. Set the Dial Type: field to T for tone dialing (the default) or P for pulse
dialing.
3. Set the Adjustable Make/Break Ratio: field to &P0 for the United States
and Canada, &P1 for the United Kingdom and Hong Kong.
Controls the make/break ratios of pulses and DTMF dialing. The United
States and Canada use 39% make and 61% break. The United Kingdom
and Hong Kong use 33% make and 67% break.
4. Set the Dial Command: field to D.
Specifies standard dialing command.
