gEDA-user: How to achive ~90us delay on a digital line

[Tamas Szabo <sza2king@xxxxxxxxxxx>]

Hello All,

Sorry, I know this question is a bit silly (and maybe off-topic).

I have been designed an IrDA interface. It works correctly if I connect 
for example 2 minicom terminal. However I need to communicate with a 
device, which echoes back all characters, but too fast - so the host 
side is not ready to receive it (Well, first I designed with HSDL 3602, 
and it was OK on the breadboard, but HSDL is not available now, thus I 
redesigned with TFDU 4300, and it has somewhat different characteristic).

If I would be able to delay the echo with a few tens of usecs, It would 
be a workaround.

I was thinking of solutions, like a uC with UART, some big fifo, etc. 
However if any of you have simpler solution, could you please share with me?

Thank you, in advance,

/sza2
