For SNA service TPs on SNA Server clients running OS/2, the line naming the TP in the SNA.INI file must specify the TP name in ASCII. The following paragraphs tell how to convert a TP name to this form. The line should be placed in the [SNAServerAutoTPs] section of the file, as shown in Clients Running OS/2.
An SNA service TP name is normally up to four bytes in length; the first byte is a hexadecimal number in the range 0x00 to 0x3F, and the remaining bytes are EBCDIC characters. The first byte defines the function class of the TP. Therefore, to convert a service TP name to an ASCII form, convert the first byte as shown in the following table, and convert the EBCDIC values to ASCII letter equivalents.
| First byte of TP name (hexadecimal number) | ASCII character equivalent for SNA.INI |
|---|---|
| 0x07 | DDM |
| 0x20 | DIA |
| 0x21 | SNAD |
| 0x24 | FS |
| 0x30 | PO |
| All others | UN |
For example, a service TP name of 0x21 0xD7 0xD7 is equivalent to SNADPP (0x21 converts to SNAD and each 0xD7 converts to P).
