[linux-cirrus] Re: Additional CTS/RTS Serial port on EP9302

Folks,

 Random question:
I've got two peripherals that require CTS/RTS handshake controls on RS232. AFAIK The EP9302 has only 1 full CTS/RTS serial port (/dev/ttyAM0).
Have any of you attached a second UART, if so, which UART did you choose and why? 

   Cheers,

We've put some small UARTs we designed in a CPLD (actually, a very small FPGA) and have developed some open-source Linux device drivers for it. Can fit up to 5 of them (with RTS/CTS) in a small $3 CPLD. For the TS-7300, which has a bigger FPGA, we designed a board with 34 UARTs (http://www.embeddedarm.com/~joff/34comm-stcllw.jpg)
