Hello netters-I have a query about the rs232 communications.In William Stalling
book"local network technology"Third edition page 48 it has the following RS232
limits.
Data Rate(bits/s)                     Distance(meters)
1.2k                                    914
2.4k                                    549
4.8k                                    244
9.6k                                    122
Source Texas Instruments.
The above rates and distances are available on RS232-C designed cable
1-What exactually is RS 232-C designed cable
2-Where did I get the figure of 50 foot maximum distance for RS 232 communications from.
maybe a special type of cable,or maybe the book is wrong.
