AX = DE2Eh DX:BX -> socket record (see #00558) 0000h:0000h to create a new socket record
Return:
CX = size of socket record in bytes DX:BX -> socket record which was used
Notes: DESQview 2.50-2.52 are distributed as part of DESQview/X v1.0x.. Socket records are allocated from common memory. For Unix compatibility, each socket and connection on a socket is allocated a DOS file handle (referencing an SFT for NUL) which is used on various calls to specify which of possibly multiple connections is to be operated upon
