My User Port RS-232 interface has a switch that can be set to either Hayes
or 1670. I have never really understood why. I thought that an RS-232
interface just converts between RS-232 voltage levels and User Port RS-232
voltage levels. I use the RS-232 interface for transferring files between my
C128 and my PC using a null-modem cable. I have set the switch to Hayes and
that works well. I'm sorry if something like this has already been discussed
in this email thread. I must admit that I haven't had time to read all of
the emails so I don't know what the original problem was.
