I was having this EXACT problem less than two weeks ago... I discovered that the serial port on the back of the DECStation is (obviously! :) RS-423 (?!???) What this means is that the voltage swing does not have to be as great as RS-232 requires. Solutions? Two that I found: 1) Buy a Telebit. They don't seem to care much if the voltage is low.... 2) Some companies are rumored to sell RS232 boosters which supposedly do the trick. I built one from 1488s and 1489s. Drop me a line if you want a PostScript schematic. -- Steve Watt ...!claris!wattres!steve wattres!steve@claris.com also works If you torture your data long enough, it'll eventually confess.
