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.
