Robert, I do not know much about programming applications using tcpip APIs. By "old vendor" software I guess you mean "no longer have any vendor support" and you do not have source code. I do not have any solutions to this. Maybe someone else will have some words of wisdom.
Speaking of port usage, here is another tip. In the TCPIP profile, TCPCONFIG and UDPCONFIG default to restricting usage of ports 1 through 1023. So a port must be reserved for any application using anything in this range or the profile needs to have UNRESTRICTLOWPORTS coded on TCPCONFIG and UDPCONFIG. Normally this range is used by standard applications like ftp which are included in the sample profile.
