Int 61 Fn 54  - PC/tcp Kernel V2.05+ - "nm_res_name" - Resolve Host Name   [N]

   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 INT 61"PC/TCP")

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.
