Re: [newtech-1] RJ11 to RS232(DB9) Cable

Wow. I am truly among the brain-dead today.

Sorry about that.

RJ-11 is 6-pin, not 4.

BTW, a quick googling of "serial cable rj11 db9"
doesn't seem to reveal a definitive cabling standard
when going from serial to RJ11; various vendors of
different gadgets (serial port multiplex hardware,
PocketPC interfaces, emulators, bla bla ) seem to
have varying serial wiring assignments. But this
was just a quick look....
