[En-Nut-Discussion] getch for Ethernut

[Joerg.Lamprecht at kendro.spx.com]

Hello,

I looking for an euquivalent for the C std. func. getch.
So I need that because fgetc and all the other i/o get hung when waiting 
for a char.
Is there any possibiltiy to set a timeout for fgetc. I tried the UART I/O 
Control Function _ioctl with the Command
Code UART_SETREADTIMEOUT to 100 ms, but my Thread doesnt interrupt. 

Greetings from Jörg
