You don't mention which Gumstix or which serial buffer. The PXA255 and PXA270 have 64 bytes send and received hardware FIFO's, what's implemented in the driver I don't' know. You should take a look for the PXA255 and PXA270 Processor Developers.pdf on the Gumstix web site. They describe all the peripheral hardware or each processor. http://pubs.gumstix.com/documents/PXA%20Documentation/PXA270/ http://pubs.gumstix.com/documents/PXA%20Documentation/PXA255/ Hope that helps, Lawrence Torchris wrote: > Can anyone tell me the size of the Gumstix serial buffer? > > thanks, > > Torchris > |

Thanks! I have Verdex and I am talking about ttyS2 off of an LCD-Console. Sorry, I should have made that clear. Acutally, I was able to sort out the issue. I am reading the serial port using PHP (using the php_serial.class.php library) and it was giving me some inconsistencies. It turned out I needed to put in a slight delay into the loop so the port could catch up. regards, Chris Lawrence Harris wrote: > > You don't mention which Gumstix or which serial buffer.
