How does this relate to IrDA with SIR speed of 115200 and max turnaround of 500ms? The max throughput is about 5000 bytes in 500ms. Garst - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.or

Hi Alex! I'm a little confused here... why are we overrunning? This thing is running externally at 19200 at best, even if it does all come in as a packet. I would think the flip buffer would never contain more than a few characters. Are you running it at a higher rate internally? Does

Serial device with very large buffer

2001-02-01 Thread Alex Belits
Greg Pomerantz <[EMAIL PROTECTED]> and I have found that Novatel Merlin for Ricochet PCMCIA card, while looking like otherwise ordinary serial PCMCIA device, has the receive buffer 576 bytes long. When regular serial driver reads the arrived data, it often runs out of 512-bytes flip buffer and
