We strongly urge you to discuss your specific need with a computer dealer if you need advice in this area. To communicate properly with the BBRC computer, certain parameters must be set on the terminal and modem. Set the baud rate of the terminal to that of the modem. We prefer that you use VT100 or VT102 if available. Most locations have 1200 baud service.
Modems operate in different manners.
Most modems now use the AT command set which can dial the phone through the terminal. With older manual-dial modems, set the data switch to on and then hang up the phone after hearing the high pitched tone. With acoustically coupled modems, place the telephone headset in the coupler after hearing the high pitched tone. Please refer to the modems operating instructions for more details. This message tells you that you have reached a data line number, and it gives you the baud rate of the connection.
