AX = 4505h DL = port number (01h = COM1) DH = error flagbit 3:
Set on error. ES:BX -> ASCIZ text to return to user, max 1024 bytes
Return:
AH = 4Dh if EMAIL installed on specified port AL = status 00h successful 02h unable to perform function (timeout, prev call not complete) other error
Notes: If the error flag in DH is set, the string is not sent and an error message is generated instead; if this function is not called within five seconds of AX=4504h, EMAIL automatically generates an error message. The string is copied into an internal buffer, allowing this function's caller to continue immediately
