Excerpt from Joerg Dietze quoting documentation from NETBASIC:
> CONNECT local_port, server_port, server_name, mode
local_port is an integer value between 0 and 9, similiar to the
file number used in the file functions
server_port is a real port number , e.g 80 for http or 23 for telnet
server_name is a string with either the name of the server or
its IP-adress.
mode is a string. Possible modes are "a" for ascii mode or
"b" for binary mode.
I don't want to quote 100 lines, but how is the local_port number determined,
especially if DOS and the BIOS don't recognize the port by an integer between 0
and 9? Like maybe a modem at base 0xd400 IRQ 11, or even base 0x2e8 IRQ 5? Is
there a form of the OPEN command that dials the modem and installs a packet
driver?
