[Gumstix-users] minicom annoyance -- characters not appearing immediately

[Michael T. <mik...@ap...>]

I'm using minicom to talk to gumstix boards across null modem cables.  
The problem I have is that quite often the next few characters of output 
from the gumstix board is not displayed by minicom until after I press a 
key or two.  Sometimes I have to keep pressing keys to force minicom to 
read the pending characters and catch up with data already buffered by 
the serial driver.  I've got software and hardware flow control 
disabled.  I've tried with interrupts set and with interrupts set to 0 
for polling.  In all cases I've never been able to figure this one out.  
I've learned to  use the left arrow key at the shell prompt to force the 
prompt to appear whenever it fails to show up, as this is fairly 
harmless keystroke to slam the gumstix with.

Thanks for any suggestions.

Cheers,

Mike
