Pl2303 usb to serial recevies but does not send....lsmod, dmesg ok
Dear all,
I have a kermit connection running between a laptop and desktop.
The laptop is connected to a Prolific PL-2303 USB to serial adapter. One end of a null modem cable is attached to this adapter, and the other end is connected to the serial port of the PC.

Everything seems fine . I conenct the 2 computers using kermit. I can receive on my laptop from the PC, but I cannot send from the laptop to the PC.
Both computers run RHEL4. I even tried replacing the RHEL4 laptop with a laptop running Fedora 9 .... same problem.
Those USB/serial devices usually work well, and 'just work'. Are you sure the cables/connectors are good? Since you've tried a different computer, that would rule out the hardware, kernel module, and other such things that could cause a problem....

The same setup works in windows using the same cables. That validates the hardware. The problem i face (can receive but not send) is only in Linux. Given our stiff deadline, this is turning into a major hassle that might force us to change our production environment to windows. I hope somebody from the community can help.
