   ES:BX -> request packet (see below)
Program: TCPOpen is a TCP/IP protocol stack by Lanera

Note:  the interrupt number may be set to any value from 60h through 7Fh
     (default 61h) via the configuration file; there does not appear
     to be an installation check, though function FFFFh can be used to
     verify that the software is indeed functioning

Format of request packet:
