ISO 8583 ALPHA is not converted to HEX

Question

Config:

<template type="0500">
        <field num="3" type="NUMERIC" length="6">920000</field>
        <field num="11" type="NUMERIC" length="6" />
        <field num="24" type="NUMERIC" length="3" />
        <field num="41" type="ALPHA" length="8" />
        <field num="42" type="ALPHA" length="15" />
</template>

Code:

MessageFactory mfact = ConfigParser
                    .createFromClasspathConfig("config.xml");
            mfact.setTraceNumberGenerator(new SimpleTraceGenerator((int) (System.currentTimeMillis() % 100000)));

            m = mfact.newMessage(0x500);
            m.setValue(24, 109, IsoType.NUMERIC, 3);
            m.setValue(41, "10986312", IsoType.ALPHA, 8);
            m.setValue(42, "000001106020132", IsoType.ALPHA, 15);

            String strMsg = new String(msg.writeData());

strMsg is giving me this result:

05 00 20 20 01 00 00 C0 00 00 92 00 00 04 42 18 10 91 09 86 31 20 00 00 11 06 02 01 32

but the result should be:

05 00 20 20 01 00 00 C0 00 00  92 00 00 04 42 18 01 09 31 30 39 38 36 33 31 32 30 30 30 30 30 31 31 30 36 30 32 30 31 33 32

where:

field 24 => 109 should be 0109
field 41 => 10986312 should be in hex 3130393836333132
feild 42 => 000001106020132 should be in hex 303030303031313036303230313332

Both field 41 and 42 are Alpha Numeric Special Character field.

Should I use HexCodec.hexEncode whole message of part of the message before sending to the host using TCP/IP?
