Int 61/AH=54h

PC/TCP kernel v2.05+ - nm_res_name - RESOLVE HOST NAME

AH = 54h
CX = size of destination buffer
DS:DX -> ASCIZ host name (max 127 chars)
ES:DI -> destination buffer or 0000h:0000h

Return:
CF clear if successful
DX:AX -> IP address of host
destination buffer filled with canonical host name
CF set on error
AX = error code (see #03319 at INT 61"FTP Software")

Note: This function uses all configured methods in turn to resolve the name (numerical, then host table, then DNS, then IEN116)

BUG: The SLIP kernel for v2.05 bounds-checks the wrong register, so values greater than 54h in AH may crash the system. Other kernels may have this bug as well; it has been fixed in the v2.2 SLIPDRV kernel.
