Re: DSelect and ftp
When Robert-Jan Kuijvenhoven wrote, I replied:
Try the command
man minicom
to learn about the minicom program for manipulating your modem. I don't
have personal experience with it, (when I need to do these things, I
write
a perl script or something to gain access to the port/modem) but I've
seen messages to this list which have been enthusiastic about minicom.
Hope this helps.
