Serial port communication
We're running SCO Unix Openserver 5.05 and I'm having trouble with serial communication between the com2 serial port and a handheld device. Downloading data from Unix to the handheld works perfectly, but the other way around creates a major problem. I don't know whether it's a buffer overflow or what, but it looks as if the handheld sends the data faster than Unix can read it. Flowcontrol? Anybody? Please help.
Thanx. |

What kind of handheld device? What's the port you are connecting to? /dev/tty2a or /dev/tty2A ? Look in /etc/inittab and look for the line that has /dev/tty2a or /dev/tty2A and see if a getty process is respawn on that port ? What's the baud rate set on the port? What kind of wiring protocol do you have ? Xon/Xoff ?
