Re: Problems with Symbol Radios and the AS/400

Patrick - is some of your network equipment not routing the telnet timemark

the other device is still connected, yet not send the packet to the devices.

Check TCP Attributes (CGHTCPA) and following parm
TCP keep alive . . . . . .

Check the telnet attributes (CHGTELNA) and the following parm
Session keep alive timeout .

You may need to check the following system value:
QDSCJOBITV Time interval before disconnected jobs end
