I tried comport under windows and get much better performance. For example in windows I can string a number of values together in a message and send it to comport. ie val1, val2, val3 . In Linux when I do this I get "Write error, maybe TX-OVERRUNS on serial line" I also tried the Linux comport object with another usb to serial adapter (prolific 2303) and get the same results? Any thoughts on this? jim
I'm trying to use the comport external in Linux and I'm finding it is quite slow. If I send 2 or 3 consecutive characters they have to be separated by about 3 msecs each using the delay object otherwise I get the message that says "Write error, maybe TX-OVERRUNS on serial line" . I want to run a fair bit of data out of the serial port so I'm using 115.2 kbaud. Could the problem be that I'm using a serial port via a USB to serial converter? Thanks.
which converter you use ?
I just play with 115.2 kbaud over the comport on linux without problems... limit to 90% to 10Kbyte/sec which is 100kbaud plus some overhead ... I use debian and the standard serial output.
maybe you post us the configuration, to know more.
