A co-worker of mine is using some of Scott Klements programs to learn to use
Sockets APIs.

She is has a workstation file to key values into fields being passed to
sockets APIs to
talk to the mail server and in the end it is supposed to return a file from
the mail server.

On her screen she has a service field and a host name as well as a command
line and a
response field. When she enters 25 in the service and Bypass (our server
name) in the
host, she receives a response back.

She then enters 'HELO'  in the command field and presses enter. The programs
goes into
a loop that executes

rc = recv(sock: %addr(ch): 1: 0)

The first 3 times it receives back non-displayable characters and the 4th
time it hangs the
program and F12 can't even exit the program.


She also was trying to key commands to talk to a couple devices we have on
the network that
required an escape character, and a Carriage Return. When she typed those
commands,
nothing happened. We are wondering when calling this environment do we need
the EBCDIC value or
the ASCII value?


Does anyone have any knowledge about these programs?
