! 108 NSR 140905 1. derived from TCPIP$TCP_CLIENT_QIO_2014E.INC
! 109 NSR 140930 1. added a declaration for nsr_dns_ghnt (get host name + type)

! see RFC-764, RFC-731 and RFC-854
! notes:
! 1. this is a partial list
! 2. used a "k" prefix ("k"=constant because "c"=char; maybe we should use "t"=TELNET).
! 3. Google this string for more information: "telnet iac sb se 250 240 nvt"
! 4. some of these numbers came from telnet.h (8.2 Berkeley)
