Packet Size
The amount of memory (in bytes) used by the workstation for transmission
and reception. If a large value is entered, a file is transferred
more quickly, but the memory overhead is larger. The default value
is 12288. In the case of Telnet3270, you can specify a packet size
larger than 8000 bytes by adding the following line to the Telnet3270
stanza in your workstation profile:
SendBufferSize=nnnn
