Call send_char from inside the serial interrupt. While in send_char do a reti. Then the interrupts are free, and you stay in send_char.

If you do a RETI, it will cause a return, so you will not still be in send_char - surely?!

Then, when you hit the RETI at the end of the ISR, the fun really starts...
