Pl2303 usb to serial recevies but does not send....lsmod, dmesg ok
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.
I ran the following commands:
find /lib/modules -name *2303*
/sbin/lsmod | grep 2303
pl2303 18757 0
usbserial 30121 1 pl2303
dmesg | grep tty
ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
usb 6-2: PL-2303 converter now attached to ttyUSB0
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.
Any help will be appreciated.
Thnx & Regards
