Question

How to increase buffer size

I have a dell laptop with XP Pro SP3. I download a dos palm pilot of text data using a serial to usb adapter on com port 1. If there is too much data to download, or if it goes too fast, I get a " buffer overflow error suggest increasing buffer size" error message. I already did adjust the virtual memory and that didn't help. (My old win 98 laptop didn't have this problem before it went belly up). Any suggestions? Don't see any option to slow down the transfer rate. Thanks.

Hi. I still maintain Palm apps.

Tell me a lot more and maybe I can help. I have never had to adjust the buffer size in over 2 decades.

It a small dos computer hooked up to a radar trailer and all it keeps is the data no graphics. It's from 1998. Since my XP Pro laptop doesn't have a serial port, I bought a usb-serial adapter. Watching it down load the info, it appears to be going too fast and I get the buffer overflow error message. Then it tells me to increase the buffer size. I didn't see any speed adjustments in the program files. Thanks.

Let me share.

I'm using the USB to serial dongle from serialio.com and given the 1998 unknown PC there is Hotsync's baud rate we can drop. I know that it is usually 115200 but try it at 19200 for a first try.

I can't say this is a buffer issue as I've never had it be that. I can take a picture of the dozen Palm devices I have in the collection for fun some day but I share because I am a developer and hope we can get this back online.

Thanks for your help. Do I download a program like Dr. TCP to adjust the baud rate?
