Having a problem with the serial object in windows. Instead of reporting no data and continuing with other processing, it hangs the application and the system until data is received. Same patches work without a problem in OSx. I have already downloaded the latest serial patches to no avail. Any ideas?

This may sound like a silly question but have you selected the right serial

port? Try deleting the attributes and sending the serial object a "print"

message" to print a list of all serial devices into the Max window. How

This may sound like a silly question but have you selected the right serial
port? Try deleting the attributes and sending the serial object a "print"
message" to print a list of all serial devices into the Max window. How
often are you polling the object?

yes I am connected to the right port. And the patch will work as soon as data starts coming at the port but if I use the patch to connect to a device that is not streaming data, like for example a gadget that sends a value when a switch is pressed, it freezes the application waiting for data at the com port. The same patch in OSx simply reads 0 values with each bang until data arrives at which point it outputs the data read. I have changed the bang rate from 1ms to a few seconds, it did not make a difference. I have been dealing with this issue for sometime now. Am I the only one using the serial object in windows xp or am I having a strange hardware problem?

I've used the serial object in XP with no problem, 20ms metro, sporadic data

input/output and worked fine. Have you tried with different serial devices?

Might be worth trying to see if it's specific to one device, or if not, then

it's definitely a problem on the computer's side.

As I said, the problem is only with devices that are not sending data periodically. Like the serial object is blocking code excution until data is received. i will try to do more tests with different devices and many pcs to see if i could figure out the problem. i am not sure if it has something to do with setting the handshake signals a particular way. I have always been using the serial object with no handshaking in the past. Thanks.

Any further info on this? Improvements with Max 5?

xp serial is still having difficulties with *virtual* serial ports.

i use a bluetooth witilt from sparkfun. hyperterminal is very forgiving with

max4/5 needs a shamen to get it working (and only on weekends).

usually it will just hang for 15-20 seconds and then will claim specified

hardware serial - like the arduino kind- show no problem.

i realise this has been a long time from being recently posted however i am having some troubles with the serial object as well. Excuse my noobness if this is simple however when i am printing the serial objects out as a message to the max window. It shows that the serial object "serial: bsd_path: /dev/cu.FireFly-13C8-SPP" I can't find any information on the bsd_path.
