Have a good idea for a new product for SFE or Olimex? Let us know!
How about an in-cable TTL to RS232, using the MAX233 IC?

Perhaps something like the following: ... apter.html

Major differences would be:
1. Would use MAX233 or MAX233A (so no external caps needed)
2. Would have funtional CTS and RTS busses.

This would result in a +5/-5 TTL to +12/-12 RS232 cable complete with CTS and RTS busses!

Might even be able to fit an led network to show CTS/RTS/TX/RX with a DIP resitor network.

led network: ... type=store

Resitor network: ... tId=120099

Maybe all that would not fit in the cable but it might in a small in-lline wall-wart (like used in laptops).
type plastic box.

OK, so the LEDs are overkill...

Cool idea - I like over-kill :D

(time to plug my own stuff) Have you checked out the shifter board? ... itemid=244 It does everything the MAX232 does but without the space needed for a DIP and the 5 external caps.

Now if you want to be really cool - checkout my buddies company Acroname: ... -CONN.html

Okay, so my buddy just works there.
