Issue

Does PASSPORT support the IBM PC/3270 PCSAPI?

Solution

PASSPORT does not support the IBM Personal Communications/3270 PCSAPI per se. The PCSAPI is used to control the Personal Communications/3270 session itself, whereas HLLAPI is used to manage communication between the workstation and the host session after the session is established.

The PCSAPI contains functions that do the following:

• pcsConnect Session

• pcsDisconnect Session

• pcsQueryEmulatorStatus

• pcsQuerySessionList

• pcsQueryWorkstationProfile

• pcsSetLinkTimeout

• pcsStartSession

• pcsStopSession

PASSPORT contains HLLAPI extensions that do essentially some of the same functions in the IBM PCSAPI. These HLLAPI extension functions include:

• HLL_RUNPROFILE - Run the Session Profile

• HLL_RUNCONNECT - Run the Session Profile and Connect PS

• HLL_CLOSEDISCONNECT - Disconnect PS and Close Session

These HLLAPI extension functions could be used to accomplish some of the same things accomplished using the PCSAPI. However, the API program would have to be modified to use these HLLAPI extension functions instead of the PCSAPI.
