So I have a very old radio modem that uses hardware flow control. Its RS232 with RTS, CTS and RTD. I have pins:
2- Tx
3- Rx
5- GND
6- RTD
7- RTS
8- CTS
My new equipment, I have no control of imitating hardware flow control.
So I put a loop back on pins 7 and 8. Its still not "going" I don't know what to do with PIN6 (RTD) because there are no other pins to do a loop back with that. And by that I mean the DB9 does not have any other pins other than what I listed. (it's a custom made cable with the push through DB9 pins, if you recall those from back in the day).
Any ideas what can be done here to get this to go?
Thanks
