I have seen an ad in the January issue of Computer Shopper about the V.42bis
external modem by Zoom for a price of $189. It claims that it can achieve
9600 bd compressed through-put with a 2400 bd data-pump; fully V.42 COMPLIANT,
100% Hayes and MNP-5 compatible.
My questions are:
(1) How does it compare to the real 9600 baud modems in terms of performance
and usage?
(2) Does it require a special kind of software to operate?
(2) What do V.42, V.42bis, Hayes and MNP-5 mean?
(3) I have seen that some modems can be addressable with COM1, COM2, COM3 and
COM4. What are they?
(4) What is the limit of ordinary phone lines? Can it handle 9600 baud data
transmission?
(5) I assume some of you know X. I have a 386/33 IBM PC-compatible system at
home. What do you think the minimum baud rate necessary of a modem if I
want to run jobs "remotely" on DECs say, and display graphics "locally"
and efficiently on my PC screen via X window?
Please use my email address in your response if possible. Your help will be
greatly appreciated. Thanks.
