AH = 04h DX = FFFFh ES:DI -> Connection Request protocol vector (see #00311)
Return:
AH = return code 00h successful AL = connection ID BH = connection type 00h direct connection or no dialing 01h Connection Server dialed phone 01h no response from Connection Server 03h invalid request
Program: Connection Manager by Softwarehouse Corp. permits the sharing of serial ports over an IPX or NetBIOS-based network
Desc: Initiate a connection to the Connection Server listed in the current Client parameter set
Notes: If DX is 0-3 on entry, Connection Manager emulates the standard BIOS function, but redirects the port over the network; if DX is any other value, the call is chained. All subvectors of the Connection Request vector are optional; if missing, default values are provided by the default connection parameter set
