Hi, I am using Telxon PTC-710 device in linux environment and I am using RS232 Serial to USB converter. When I connect the device to USB port it is detecting and showing in the system log as "attached to ttyUSB0". I have written a java program to display all the available ports. But this program is displaying only ttyS0 &ttyS1. I have tried to set all permissions to the user as well as to port. Please help me if I am missing any configuration related to this driver. I look forward to hearing from you.
