For example, on some systems the lack of a *real* System Console will cause the system to power-down or panic...this can happen if the terminal is turned off, e.g. ----In addition, you might want to have a modem as the console and to appear to have DTR ready, but a modem is not a DTE, but a DCE...this adapter is constructed to allow remote access to the console with the above mentioned gotchas taken care of. > -and- >355 AF -----Another protection device...the 355 A has both resistors and diodes to protect *precious* equipment. I have seen it on ISN's especially, since the range of the net can be so large that the exposure to harmful electric stuff is greater...this RS232 adapter supposedly protects the equipment; I believe that it comes in both ACU/Modem Male/Female and Terminal/Printer Male/Female. I don't think that there are Remote/Console 355's. > >What are these?
