Hi,
it doesn't work. MTU is 4400 and XMITBUFSIZE is 8232 (see online manual "TCP/IP
for OS/2 Command Reference", search for
"mtu n"). Our network guy sniffers the communication between the OS/2-client
and the MVS-server. During TCP-initialization the
OS/2-client says the server "512 byte is my MAXTCPFRAMESIZE". I guess 512 byte
the minimum / default setting for this
parameter. Any idea ???
