Is there any easy circuit to program PIC and/or PICaxe without an RS232 port, which I do not have? Answered

I have a USB-TTL cable which I use to program AVRs, and if there's a PIC porgrammer that uses a TTL input, it's perfect. I know you can get USB-RS232 converters, but I'd really prefer doing without RS232 all-together. Thanks in advance!

Why can't you use your USB-TTL (RS232) lead to drive the PIC programmer ?

I was looking at circuits for PIC programmers, and looking at the inputs to it from the RS232 port, labeled such as RTS, DTR, CTS, TxD, etc., then compared them to the outputs from my TTL cable, labeled Rx, Tx, 5v, and Ground. I understand the 5v and Ground, but can't understand how to wire the TTL cable outputs to an RS232 programmer. As in, which output from the TTL to which input on the RS232 programmer?

Rx goes to cable TX, Tx to cable RX...+5 to your local supply, and GND to cable ground and

Thanks, I'll try this and hopefully it will all work out.
