High-Speed Modems
Specific System Requirements - High-Speed Modems
If you have a SwiftLink RS-232 cartridge or you are emulating it in VICE, you can take advantage of a high-speed modem, communicating at rates of up to 38,400 BPS. There are many different types of high-speed modems, some of which may not be compatible with others because of the diverse "standards" set down by different companies. If you plan to use a high-speed modem, you should invest in one that can handle many different communications protocols. Some of the more common protocols are V.32bis and V.42bis.
Also, if you plan to take advantage of the error correction and data compression features of a modem, you need to check the modem to see if you must adjust the computer-modem BPS rate to be the same as the modem-modem BPS rate. In many cases it is better if you can set the computer to modem communications to the highest rate, no matter what the modem-to-modem communication rate is. The "Adjust BPS" question in setup determines how the computer will react when a call is received. If you answered "Y" to the question, then the computer will always match its own BPS rate to that of the "CONNECT" message. If you answer "N", then the computer to modem rate will remain constant and the modem will handle the necessary conversion.
