In the RFC for the Telnet Window Size Option (NAWS), it says that "The
subnegotiation consists of two values, the width and the height of the
window in characters. The values are each sent as two bytes, in the
Internet standard byte and bit order." The syntax for that subnegotion
is the following:

IAC SB NAWS WIDTH[1] WIDTH[0] HEIGHT[1] HEIGHT[0] IAC SE

Which I find strange because [1] comes before [0]. Using that syntax,
the following line gives a width of 80 and a height of 24:

IAC SB NAWS 0 80 0 24 IAC SE

But this line gives a width of 300 and a height of 24:

IAC SB NAWS 1 44 0 24 IAC SE

And that is where I got lost. How does "1 44" equal 300? Thanks in
advance.

Nevermind, my question was answered elsewhere. Thanks anyway.

300 = 1*256^1 + 44*256^0

Therefore "1 44"(base256) = 300(base10)
