I generally insist on keeping a "true" v.35 interface somewhere between the two devices. This provides a point at which I can plug in test equipment without changing any cables. It also makes it much easier to replace the box at either end -- there's no need to worry about subtle differences in DB25 pin assignments, and it puts the onus for cable compatibility on the vendor. : -- : Jim Reilly : FastComm Communications : 1-703-318-4385 9-6 EST : jreilly@fastcomm.com Andrew Birner Zenith Electronics Corporation (847) 391-7926 Andrew.Birner@ZenithE.Com -- ------------------------------------------------------------------------------- Andrew E.
