that must have been before Ray Gwinn (yes, the x00 fossil author) released SIO
for OS/2... SIO brought the entire virtual modem thing to the market... it was
the first, best and most reliable virtual modem implementation... winwhatever
users suffered for many years before a proper one for the NT kernel stuff was
available... most of them, however, only did telnet... SIO brought telnet and
vmodem at the same time and two SIOs with the same registration number cannot
connect with each other... piracy prevention, ya know ;)

yup... AFAIK SIO on OS/2 is the only way one can use the vmodem protocol...

to avoid the scanner bots on port 23, choose any other port... you can use 3141
if you like... i was just pointing out that vmodem normally runs on that
port...

rc> Hmm... well..I guess I will be finding out... VM's are CHEAP! :) ;)
so they say ;)

rc> Never played with it before... so I can't speak to it either.. Right

rc> Memory Manager) in there for EMS/XMS stuff... like I said it really is

hahahaha... i'd probably fall back to QEMU from quarterdeck because i know
it... no clue if it would even work with today's stuff, though...
ml>> FD doesn't have a problem dialing domains... i actually set mine up to
ml>> dial some with telnet and others with vmodem ;)
rc> Really??? I would have expected that the input would parse for 0-9 and

rc> letters..hmm....
joho was very forward thinking... frontdoor was the first to offer this
capability...
===== fdnode.ctl =====
[snip]
DIAL / 011-
# internet
0000- internet/:115
000- internet
V internet#
[snip local calling replacements]
END
===== end =====
then phone numbers can look like this in the nodelist or the overrides...
the '#' signals for a telnet connection... the 'V' for a vmodem connection...
'000-' is also telnet... '0000-' is telnet to port 115... in retrospect, using
'V' for the vmodem protocol is not a very good idea because of the confusion of
the meaning of the character... probably better to use another character that
is not allowed in domain names... '@', '%', or '^' seem to be better choices
for the 'V' in fdnode.ctl and in the phone numbers in the nodelist and
overrides...
frontdoor development stopped before the nodelist INA flag was put into use so
a lot of stuff has to be done manually instead of reading from the nodelist
unless someone wants to write a tool to convert the distributed nodelist to the
form that frontdoor can read directly... it is easy enough to do and there are
still examples using '000-' as their areacode to signal that the following
numbers are an IPv4 number... IPv6 is different and requires additional
conversions... SIO doesn't do IPv6 and frontdoor shouldn't care because it
thinks it is talking to a modem...
NOTE that the above numbers and domains are just examples... nothing more...
