Hi
I'm trying to build a simple system with a microcontroller and 2 RS232
ports to receive data on 1 port and send out new data on the 2nd port

requirements are
1. 2x RS232 UART port, configurable comm settings
2. 64k internal memory to store the RS232 strings database
3. 2x 8 bit IO port to select options using 8bit dip switches

I've worked with an 8051 many years ago and from what I've been reading
again, it looks like it should do the job quite well.

any advice? a development kit would help too.

thanks
Lim

Have a look at various Zilog parts.

I used to use the Dallas DS2252(T), serial in/out on TI/TX and bitbang
on p1.x for the other port. With the internal ram you can compensate
for speed problems.
